Probably (there are caveat cases where that might not be true, but usually
you are correct).

My Pages Output/Sec spikes when my % Disk Time spikes, = I need more RAM,
right?

RAM will help (up to 4GB) iff the problem is that you don't have enough and
the system is paging. Use the performance monitor in the administrator
tools at monitor paging to see if it correlates. (Also you can look at the
"available memory" in the task manager to see if it gets low).
By the way, given both CPU and Disk activity, you likely have more than one
performance problem.

We have 6 MF XP servers FR3 win2k sp4. All are DL360's with 1.4 GHz procs
and 2GB RAM (3 G1's and 3 G2's) We are having a very similar problem where
users will notice delays or screen hangs for 10-20 seconds in their ICA
sessions while in any number of applications. I see using perfmon that my
CPU utilization will spike at the same time as my % Disk Time will spike.
Would you recommend trying to go this route to fix it (adding write cache to
my Raid Controllers) or do you think that I could simply add more RAM to fix
this problem (we have already ordered the RAM so...)
Thanks,

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.

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.
