Sluggishness

[solbjerg]

Hi all

I am experiencing some sluggishness in the forum the last couple of days - is it just me?

XP - IE - MSE (all fully updated)

Cheers

solbjerg, for your information, I have not seen any sluggishness in the forum lately either with XP - IE8 and FF 3.63 - McAfee or, W7 - IE8 and FF 3.63 - Avira.

 

Cheers.

Thanks enoskype

It must be my own machine then - I'll see if I can find a reason for it then.

Cheers

possibilities :-)

 

Hi

I did a chkdsk and a sfc /scannow

This seems to have helped, but perhaps I have a problem with my mouse - I will try a new one.

Cheers

Hi solbjerg,

 

If the clicking of the mouse is OK, then I don't think it is because of the mouse.

 

Why don't you show us your www.speedguide.net Broadband=>Broadband Tools=> SG TCP/IP Analyser result, it can give a clue about the internet behaviour.

 

Cheers.

Hi enoskype

Ok here it is:

« SpeedGuide.net TCP Analyzer Results »

I then used the optimizer in ASC and got this result after a restart:

This helped making it much less sluggish! Thanks!

Perhaps it can be configured to do even better?

 

I then tried it with this setting:

Haven't noticed any improvement from the previous setting

Hi solbjerg,

Why don't you show us your www.speedguide.net Broadband=>Broadband Tools=> SG TCP/IP Analyser result, it can give a clue about the internet behaviour.

Hi solbjerg,

 

Can you try it with:

All values the same but,

RWIN=128480 and/or 64240

TTL= 75 in both cases. (In Internet Booster.) (It should show 64 in the analysis.)

 

Which bandwidth is your connection?

 

Cheers.

[solbjerg]

Hi enoskype - Thanks!!!!

My bandwidth is 10 Mbits/s but I have never seen it higher than 6,8 - right now it is 6,6.

The 64240 feels as if it is the best in what little data I have to evaluate it from :-)

[enoskype]

Not at all solbjerg.

If your bandwidth is 10 Mbits/s but you have never seen it higher than 6,8 Mbits/s, taking into consideration the latencies, I would go for:

RWIN=256960

and

TTL=75 (In Internet Optimizer and 64 in the analysis.)

 

if I were you.

 

Cheers.

[solbjerg]

hi enoskype

Thanks a lot!

I will try that again :-)

Perhaps we/you should move this thread to ASC if you think others could benefit from it.

Cheers

solbjerg

p.s. RWIN → Recieve Window; TTL → Time To Live
