PC performance slowdown using Notes

We've installed Notes as our email system on over 20 Windows 98 PCs.  We have trouble with about half our systems slowing down throughout the day, until finally the mouse pointer begins to move in slow steps or not at all.  Some systems do not have any performance problems at all while identical hardware (GP6-450) will slow down throught the course of the day.  Clock actually starts losing time, today mine lost 10 minutes, some weekends I leave it on and it's lost 45 minutes by Monday.  We thought we might have identified the problem as an active qnc.exe file, but apparently not.  Any other ideas?

Try to change:
TCPIP=TCP, 0, 15, 0
to:
TCPIP=TCP, 0, 15, 2000, 12288
In the notes.ini of the workstation.  

I saw this in notes.net before and it boosted my client's performance.
By the way whats the RAM on those systems?

RAM is 128Mb.  You don't give an explanation as to what this parameter change does to the system, why it should improve performance.  This cannot be the source of the problem I am experiencing, since I checked our systems that do not have the "slow down" problem, and they have the same TCPIP setting as my system does.  Your solution may improve performance, and I may try it to see if we get an improvement (always willing to make overall improvements), but it does not account for only "some" of our systems having this problem while others work fine.  The most significant symptoms are the gradual performance degradation over time (hard drive begins working harder, mouse pointer begins lagging, worse as the day goes on), and you will see the clock begin losing time, 10 min or more per day.  This occurs only on part of identical PC's that were purchased at the same time, and Lotus Notes installed in  the same period of time.

Contact your hardware vendor and explain this problem. It should be an hardware problem, not an software problem.

yes!!! I suggest u try it first.  You have to see those machines are on which part the network, I suspect this is a network problem.  If the machines are not, then I dont think its a network problem anymore, maybe in the hardware as Hemanth said.  Could be that the harddisk on those machines is getting full, as the windows page buffer size is increasing.  Maybe you should check to see if the harddisk is partitioned and win98 is assigning virtual memory to the partition that have the windows directory (by default), maybe this parition is full or near full, try to change this.  In my personal opinion, WIN98 is the worst release of Windows, lets say a transition to WIN2000.  The syptoms u provided are weird, but it seems that the CPU is so busy with some task that it cant even keep up with the clock.  Maybe too much network traffic on that segment, or condensed network.  As for the explanation of this: TCP is the driver name for the port, 0 is a placeholder, 15 is a also a place holder that is used with other ports, 0 or 2000 is the data buffering for the application which defaults to 8000 (before u change it to 2000), the last number is for the scurity layer.  There is a technote in Lotus support website that goes into more technical detail if you care to search for it.

Those are some ideas.

On the mail databases (and any other large databases) check the full text index settings and check the server indexer to find out if it is trying to index databases and failing.

I have seen this happen with large databases where a lot of the information changes daily and the full text index is set to run immediately.  The server cannot keep up indexing as the data changes and gets into more and more tight loops until...it nearly stops.
If you go to the server console and issue a "drop all" and see if performance starts to improve (drastic but it works)...note that I have seen the server take 40 minutes to recover.
If you are on NT then look at the performance monitoring and you will characteristically see the CPU running high, no free memory and a massive amount of swap file being used.
You can be even more drastic and pull out the network cable (making sure noone can get back to the server) and see if over time it rights itself.

Other possibilities.
Choose the 'Island' location for some of the faulty machines and sit back and see what happens.
On some others check the preferences to see how often mail is being checked for.
On the server, check what db's stat rep, adminP etc are looking at and how often.

This sounds like a memory leak.  Your system is running out of memory and all applications begin to run in virtual memory.  

I need some information before going further:

1) What version of Notes client are you running
2) Are you running antivirus software ?
    If so, does it scan all files that are opened or just program files.

3) If you don't start the notes client on one of  the problem stations, will the problem still occur ?

Response to vicmcse
1) I'm running 4.6
2) Yes, Norton AntiVirus v5.0   - options selected -> scan a file when: run, open copied or moved, created or downloaded.  What to scan: program files.
3) I don't think we've tried to run one of the PC's long enough without Notes running to see if the problem doesn't surface, but we have canceled Notes once the PC begins to slow down, and good performance seems to be restored or at least improved.  We did not continue to run the PC without Notes to see if peformance continues to degrade over time. ( MS Word FindFast has been removed from startup on these systems).  The way I have been able to accelerate the degradation in performance is to open several messages (sequentially) and launch and close their attachments (sequentially).  After a couple dozen of these,  the mouse begins to freeze momentarily as you move it across the screen, and if you let the system run for awhile you notice the clock is losing time.

Is the slowdown whilst using mail or another database with attachments?
I still think the problem is with the server set-up/indexing and not hardware.

I'm going to try to reproduce your problem.  What's the minor version of your notes client ?  (example 4.6.3a)

answer to phooey:
I *seem* to be able to accelerate the slowdown process by launching applications from Notes to view attachments to Notes messages, and then closing those attachments.  After many repetitions of this, I begin to see performance slowing.  The performance slowdown is then evident in any task I do on the PC.  When it gets extremely bad, (hard to point mouse because of the "lag" in mouse movement), I can close Notes and get improvement.

Hi RoyM

After you launch the application (several times), don't close notes but clear all the files from temp directory and see if you can have a enhanced performance.

Accoring to Lotus, The first version to be certified under Windows 98 is 4.6.2a. The QMU from 4.6.2 to 4.6.2a is available at the following URL

http://www.notes.net/qmrdown.nsf/b95e4da8e2539eda852566cd00713f75/74557c8ffcab3616852566b90068721c?OpenDocument

Please download the upgrade to one of your clients having the problem then test.  This QMU has a fix for objects opened using OLE.  Even though your problem is not quite this case, It's been my experience that these types of leaks go hand in hand with applications that launch attachments.

Hmmm... It's been a while but I don't remember accepting the answer given by vicmcse.  I did try ghassan99's tcpip parameter change, but it did not solve the problem, system still slows down.  As far as upgrading to 4.6.2a, I would need to get the ok from our central support office.  I did contact our support, and they had me rebuild indexes and defrag and tweak some other settings, but now I do still have the problem.  They also said to be sure not to close Office applications, just close the files but not the applications.  I'm giving this a try now to see if it helps.  The answer vicmcse gave may ultimately be the "fix" but  I'm not to the point where I can try that yet.
