Subject: [THIN] Network Optmization : Output queue length very high
Ok some setup and background:
About 150 users in various sites through out Michigan and Wyoming with a
balancing of about 10 to 20 users per server at a time.
6 citrix servers with Win 2k sp4 Citrix Xpe FRx3 SP 3 dual Xenon's with 2
gig RAM Broadcom Gigabit NIC 1 file / primary ad server with Win 2k sp4 dual
Xenon's with 2 gig RAM 3Comm Gigabit NIC 1 SQL server with Win 2k sp4 SQL 2k
dual Xenon's with 2 gig RAM and 3Comm Gigabit NIC 1 file / print spooler /
secondary ad same as above
Anti-Virus Computer Associates Inoculate
Running applications in seamless using a frame relay connection to remote
offices on 56k up to 256k connections even some dialups running through our
NFUSE portal.
Applications include all MS office apps, MS streets, MS publisher, ABARA
payroll, PSI propane program, Landmark Aries, MAS 500, Crystal Reports, JJ
Keller Drug Testing, JJ Keller Maintanance, JJ Keller Driver File, Qquest
Maintance, FAST CBM, FAST Piper, FAS, CSI.Road Trucking Software, Adobe
Reader and WinZip.
The problem(s):
The main problem is what we are calling stuttering. This is where the user
types in a word and it can take 3 to 5 seconds for it to appear. Also,
sometimes a user get locked up in an application and cannot do anything
until we log them off the server but all other users on that server are
having no problems. We were looking at Brian Maddens Optimizing TS servers
and all of our settings except 1 seem with in
normal range. The one is the Network Interface Output queue length.
It is over 3,000,000,00 most of the time and can spike up to well over
4,000,000,000. That is right the billion marks. By everything that we see
and read we should not be able to communicate with the servers at all and
our networks should be down. We do have 802.1p compliant switches and have
enabled that on out network cards. A couple now show quick drops to 0 but
right back up to the 3,000,000,000 + mark. In addition we contacted
Microsoft and got the hotfix talked about in Kbase Article 822226 - Output
Queue Length Performance Counter Value Is Not Reliable on Computers with
Symmetric Multiprocessing (SMP) Architecture and applied this to one of the
servers and now it has dropped down to the 700,000,000 range. Any ideas?
Are we barking up the right tree with this?
