Sluggish IE after installation of ASC Pro

[Matt]

I have noticed a huge increase in speed but i followed vnman's guide in changing a few settings in Firefox (about:config). At the moment im so happy, the only thing concerning me is the MTU sitting at 1400. In a previous post addressed to garybear, you said a DSL modem maybe be blocking the throughput , im going to ring my ISP Monday morning and find out the story. Im also going to upgrade the ISP package to increase my download to 8Mbit/s hopfully commencing next week. Then I may need to call on you again. I want to thank you for helping me and also enlightening me on this subject.

 

enoskype gets a thumbs up from me.

Thanks for the feedback and thumbs up Matt,

 

Now I can tell you that, your MTU=1400 is OK, as you are using Point-to-Point Tunneling Protocol (PPPTP in fact PPTP). It is the max. size for it.

Please increase your TTL to 77 in FirefoxTCP Optimizer, so you can get TTL: 64 as a final result until you solve the MTU issue if you use different protocol (PPPoE, ie. Point-to-Point Protocol over Ethernet) in the future.

 

Together with what your ISP says, please give me info about your Network Adapter's properties, under Advanced tab, where you can find in:

 

Right click "My Computer"=>click "Properties"=>"System Properties" window=>click "Hardware" tab=>Device Manager=>click "Device Manager" button=>"Device Manager" window=>click + sign of "Network Adapters"=>right click "your connection adapter"=>click Properties=>click "Advanced" tab=>list all the properties on the left with corresponding current and alternative values on the right.

 

Have a nice hunting.:lol:

 

Cheers.

Hi enoskype

 

After having a lengthy talk to my ISP, they informed me that PPTP MTU is only 1400. Exactly what you've just told me.

 

With my new package advertised at 8Mbit/s PPTP MTU=1400 I will only recieve 6144Kbit/s due to me being along way away from their server. I asked for a cheaper price, they said that i didn't need to pay the change over fee which was 73 Euro.....:shock: and happy.

OK Matt, thanks for the info.

 

Everything seems to be allright in properties of the adapter.

 

Great that you are going to upgrade to 8Mbps as free. :-D

 

We will see if we can optimize your connection when you are connected with your new gear.:-P

[IcyFrostPyro]

oooooooo my connnnnection spppeeeeed is 100 mbps too but i didnt click modify all network adaptors and didnt check windows scailing what are those for?

[enoskype]

Hi Matt,

 

Well done, you have optimized your Internet TC/IP settings with your new higher speed connection.

To measure the real time speed, you have done OK, between Austria and Germany, downloading ~5MB in ~8seconds is very good, also, you can try free MySpeed PC Lite Edition or MyConnection PC Lite Edition programs from Visual Ware to measure delays etc., with different servers in USA and UK.

 

For the screenshots, normally I use standard Window's Paint program with fairly good results, and I don't know what garybear is using.

 

 

Hi IFP,

 

Modifying all network adapters, gives the permission, (fx. MTU change) for the adjustments to be applied to the Network adapters you are using for connection to the Internet. They may be a network cable adapter or a wireless adapter, etc.

 

For more efficient use of high bandwidth networks, a larger TCP window size may be used. The TCP window size field controls the flow of data and is limited to 2 bytes, or a window size of 65,535 bytes.

 

Since the size field cannot be expanded, a scaling factor is used. TCP window scale is an option used to increase the maximum window size from 65,535 bytes to 1 Gigabyte.

 

For today's connection speeds to Internet it is a regular setting. In the beginning of XP era (Win98, 98SE so on), it was limited to 65,535 bytes.

 

Cheers.

Hi Matt

About screenshots

I usually use Microsoft Picture Manager (Office 2003) as a relay station, where I click optimize picture. In some situations I use Paint too like enoskype.

Hello friends. I have HP PSC 1350 all in one printer, and it has a screen print option . It stays on my tray all the time . That's the only way I have ever used screen print,and the only way I know how.

Lol sorry to scare you,

I wonder if you could put that into one of your ASC skins for me....now that would be scary.

 

I,ve just downloaded this http://www.gadwin.com/download/ which is all i need but the pics are still blurry :-(

maybe im doing it wrong?

ALT held down/ press Prt Scr/ open program (paint or my gadwin)/ paste/ save as / open IObit.com forum/ attach files = :sad::sad:

 

BTW @ enoskype i tried the MyConnection/Speed PC Lite Edition....hey thats a cool program, i like graphs and pics especially ones that move. Only problem is that comodo found and blocked a possible Heuristics type exe. After submitting it to their online diagnostic it came out clean. :-)

I have DSL ,with comtrend modem, Speed100.0 MBPS ...

 

I'm just curious, garybear... what service provider in Oklahoma offers a 100Mb/s speed internet connection?

 

I'm in Ohio and the most I can get here, without some T1 line or something, is from AT&T. Their highest advertised speed is 18Mb/s. I have their 10Mb/s service because their 18 only delivers about 14.5 and their 10 delivers about 9.9. Hence, a much better value. Maybe if I optimized I could get more out of the 18. Hmmmm....

 

Anyway, TxIA for the answer.

[enoskype]

Hi nuclearmage,

 

Your adjustments are good for 1Mbps connection speed, and you are not using PPPoE.

You can not use Internet Booster for Vista OS.

 

Did you change the:

Client OS: Windows XP

to

Client OS: Windows Vista?

 

If you did, good idea to give the correct information, as that page gives false OSs sometimes.

 

Only one progress you can do is, to decrease the TTL value to 64, or to increase the TTL value to 128.

I wouldn't bother if I were you though.

 

If you decide to have a higher broadband connection in the future than, we can look after the results of the speedguide.net again, as RWIN value might have a greater effect then.

 

Cheers.

[CrazyTim]

Is enoskype listening?

 

enoskype,

 

You seem to know a great deal about this area. I'm impressed! I haven't much played with RWIN values and such since back in the Win95/98 days when there seemed to be all kinds of WinSocks, in a variety from agile to plane black gold toe to just white sweat socks (with or without the Nike swoosh). :lol: LOL Getting them to work consistently seemed to be akin to a hobby of sorts.

 

Anyway enoskype, is there some kind of controversy presently about what the best TCP Receive Window (RWIN) value is? I'm asking because I'm getting three different suggested values atm.

 

ASC Pro's Internet Booster is suggesting 652620.

 

The TCP Optimizer program available form SpeedGuide.net is suggesting 513920.

 

The Tweak Tester II at Broadband/DSLReports (http://www.dslreports.com/tweaks) is suggesting "Choose RWIN between 94900 and 251120."

 

I have a 10Mbps (advertised) connection from AT&T. It's their U-verse service. It is NOT PPPoe. It's a VDSL service/modem with G.993.1 protocol. Ah yes... Windows XP Pro.

 

So, enoskype, if you want to enlighten me about the different RWIN's, just give me your thoughts, or suggest the best settings for me, I'm all ears. (Well, mostly horns, but ears too.) :-)

 

Thx!

[enoskype]

Here I am!

 

Hi CrazyTim,

 

At the end of the day, you have written the truth, noting but the truth on your last sentence of your post. :razz: LOL

 

Joke apart, your post is a great one giving every detail for us making me obliged to give a correct and comprehensive answer. It may not be precise though.:-P

 

After all those experts giving different suggestions, makes it harder for me to give you a suggestion.

 

Seeing that the download speed of ~11Mbps with 48ms delay for ISP's 10 Mbps max connection allowance, your connection seems to be very good indeed. You are lucky with the connection type with 1500 MTU.

 

OK, assuming all the other variables are taken into account as optimum (most important for RWIN to be multiples of MSS), optimum RWIN value depends on the latency (delay) for your connections.

 

Your being in Dayton Ohio, the speedtest is measured with a server ~50 miles from you, so the latency is quite low as 48ms.

 

For example, my pinging roundtrip to Richardson TX for AT&T SBC internet services is avarage 267ms, max. being 421ms and min. being 190ms, ~7400 miles going through Europe, Atlantic, Noth America and to the destination.

 

I have given those examples to give an idea of the RWIN for a virtual comparison.

 

Suppose that I had exactly the same configuration with you, the optimum RWINs would be different, mine being lower, and yours being higher to connect to the same spot.

 

Beeing in US, and assuming you are connected most of the time to lower latency addresses, I would suggest the higher edge of the RWIN values for you.

 

Coming to the reality, with your 10 Mbps connection speed, my suggestion for your RWIN would be 513920. (Even 1027840 can be tried because of low latency.)

(MY RWIN in above case would be better with 256960 value.)

 

According to Tim Xue, the author of ASC, Internet Booster is pinging in real time to adjust the values when you use auto, and I think that's why it found a higher value of 652608, but not optimum, as it is not multiple of MSS. Perhaps an indication of lower latency connections for you.

 

Broadband's DSLreport is effected by your unpingable IP address, and that may assume a higher latency giving advice of lower RWIN values.

 

Only trial and error will tell you which one is better. This is true for TTL value also.

 

TTL values are sometimes volatile, so try to choose a value to see in real time 64 in Speedguide result. Please try to increase your TTL value in Internet Booster or TCP Optimizer to 78 and see the result in Speedguide net.(try for TTL real time value of 128 also. (142 in the adjuster))

 

I would appreciate if you give information about the trials.

 

I wouldn't agree more to your comment.

"(Someday they will make a computer that totally takes care of itself. Then none of us will have any fun any more.)"

Well said my friend. :-D And thanks for the good words for me.:oops:

 

I am so happy that • Growing up is optional.

Eno,

 

Sorry to take so long to reply. I was sick for a few weeks, then I've been working on my own the last several days reviewing what ASC changes and checking on if it would fook up my `puter. The good word is it doesn't seem to... after I finally let Maintain Windows and Diagnose System pretty much do their things; and I only found a couple changes I wanted ignored (personal preferences, not problems) under those areas. e.g. Smooth scrolling, and animation when minimizing a window to the taskbar.

 

It's not really worth that much to past the Speedguid.net speed results. They vary all over the place, from ~500kbps to ~8mbps, depending on the server I choose. None of them are really that close to me (Michigan, the closest, is ~350 miles), and I'm as likely to get a better speed from Europe than here in the USA.

 

If you want them anyway, here's that Dearborn, Michigan example from hostkitty.net 2...
