[THIN] Re: Windows 2003 Terminal Server performance tips for IE?

The profile does not travel over the 56k link is not a factor  - I do agree
that a 50mb  ROAMING profile is far too big - but I'm not sure if Rosemary
is talking about roaming profiles anyway ....

The real problem, I believe is the perceived performance of IE run on a
terminal server by a client on a 56k link.  From personal experience that
can be painful!  Not too much that can be done as it is mainly an issue of
the screen re-draw on the client.  Largely this is dependent on the
specifics of the particular websites the client is visiting - lots of nice
graphics (particularly animations) = very poor performance for the client.

Forcing off-screen composition in IE will help a little.  If your clients
are visiting the same websites regularly setting a reasonable size bitmap
cache on the client could help (again it all comes down to what the website
is doing) and would be worth testing within your environment (start with a
5-10mb cache and test it to see how it goes.  Reducing the colour depth and
resolution might help as well (anything to reduce the amount of data that
must travel over the 56k link.

What type of link is this anyway? Is there any money available to "fix"
this? I seem to recall a recent  thread on one of the mail lists I'm on (may
have even been this one) about some new devices that dramatically improved
data transfer over slow links.  Can't recall the specifics but it involved a
form of "intelligent cache" that minimised the amount of data that had to
travel across the wire.  Someone may recall more details?

Good luck ...

A 50mb profile on a 56K link, sounds like a bad move to me.  Is there a
reason why you need to store so many temporary Internet files?
Hope this helps.

Hi

Speed is OK on LAN via WTS.  Extremely slow on 56k modem (I know its a 
ridiculously slow link) but I was expecting the speed to be much better.

Also slow on 256k link.

The IE cache goes to the default location - profile I believe.  I have 
reduced the temporary internet files to 50Mb via GPO - no other changes
were 
made.  There are no files in the cache.  Its just sluggish and slow in
IE 
via WTS - IE is much faster if running via the local workstation browser

I just wanted to see if there were any tweaks that would increase the
speed 
and make the experience more responsive.  Im trying to migrate a small 
office off local apps to a Windows Terminal Server.  Users won't be
happy 
running on a browser which is 2-3 times slower than their current
setup..

What bandwidth are you using? Are you on a Lan or remote?
If you're remote then it don't surprise me that a 2MB graphic takes a
while - Terminal Services is not a great  solution for graphics-type
tasks.
With IE6, you might check where you've directed the Cache - if you've
just pointed Local Settings to a netwrok share, that might cause
problems. Again, though, if you're downloading big graphics it will be
slow.

I have had one user complain about internet access speeds. While
investigating I looked in his cache and discovered some very large
graphics files of not entirely clothed females. I merely mentioned that
"Large graphics files may not work as well over TS as on a local
machine".:)

Hi

I have a 2003 WTS I need to fine tune.  Server runs std office apps -
Office 2000, Project 2000, Visio 2000, Access 2000 etc.  All these apps
seem to run at respectable speeds.  I have disabled all animation,
removed actors etc and also looked at some of the documentation on Brian
Maddens site and implemented accordingly.

My issue is mainly with IE6 performance.  It runs really slow via
Terminal Server (runs fine on the LAN outside of TS).  Also have speed
issues when viewing JPG files.  Takes quite a while to load a 2Mb Jpg in
Photo Editor or the Picture Viewer.  I am the only person using the
server at this stage and the server is specced as follows:

CPU 3Ghz x 2
RAM 2Gb
Raid 1 disk config

The images load but very slowly - u can see the bar slowly scroll across
the screen (I was expecting much better performance).  Im running the
latest MSTC client.

IS there anything obvious I can do to improve IE and JPG loading
performance?  Any GPO I can set?

Thanks
Rose
