50:50 works fine for us. if you set it to 100% read you won't need 
the cache module.

This is awesome.  I think this may solve it for me as well.  Just curious, in 
terms of TS/Citrix boxes, is it always best practice to set your read / write 
cache ratio to 50:50 instead of 100 % read?  Why or why not?

We had the same problem.  The cache module fixed it.

had the same problem on our dl360's. did you buy them with bbwc module?
found 
out that the raid controller comes without write cache. check physical disk 
%disk time during normal operation and user logon / logoff. the missing 
cache can cause the server to stop responding for a few secs. see CTX103277
for details.

Subject: [THIN] Typing Delay - Need some expert advice......please!!!!

Hi everyone,

We're experiencing intermittent (but frequent) typing delays on both of our
Citrix environments (one production one soon-to-be-production) but I feel
I've been down almost all of the normal paths.  Here are the stats:

Production environment: 5 servers, DL360 G2s, MF XP 1.0, Microsoft Windows
2000 Advanced SP3 + KB324446, KB824146, KB81669 Hotfixes, 2GB RAM, Office
2000 Test environment: 6 servers, DL380 G4s, MF XP 3.0, Microsoft Windows
2000 Advanced SP4 + All hotfixes (as of last week) + all Citrix hotfixes,
Office 2003

In both environments, we get occasional typing delays from users for a few
seconds when they're using email (Outlook is editor, not Word). CPU/Memory
are both fine during the reported sluggishness.  Network latency is well
below the threshold as this is happening even on the local LAN segement.
I've run bandwith and ping testing and this comes back with 890 MB/sec and
less than 1 ms delay time.  Port speed and duplex has also been locked down
on the server NICs and switchports.... But we're still having a noticible
issue.

With the non-production boxes, only a handful of users are on them, so maybe
1 person per server and there's still a problem... I'm at my wit's end and
I've already opened a ticket with Citrix, but it's a painful process since
it's only an intermittent issue.  Speedscreen is not turned on.  As I
mentioned, since users on the same subnet with a Gigabit connection are also
having the problem, I don't see how it can be bandwith/latency related. I'd
rather not mask the problem before actually finding out the root of it. I've
tried disabling all of the Citrix virtual channels and still no luck.. 

Has anyone else had this happen?  Any ideas on what I might be missing? Does
this sound Citrix related or network related?  Any gut feelings? Any help
would be greatly appreciated.
