Commerce Server #users? |
|
|
We're doing performance testing on a Commerce Server 2000 site, and the
automated testing tool we're using shows a marked loss of performance after
60 simulated users are active. Up to 60 concurrent users, performance is
acceptable, but after 60 it tanks. Can anyone think of a reason why this
might happen?
Thank you. |

Which components of Commerce Server are you using?
Have you identified the bottleneck? SQL/CPU? Is there blocking the DB?
Does througput go down, latency go up, or both?
Are you sure the test tool is simulating unique users and you are not
inadvertently getting multiple concurrent requests using the same UserID
(in which case you will hit problems with blocking on the transactions
tables).
Troubleshooting performance and scalability issues is not trivial. There
are resources in MSDN related to this, I suggest you learn more about what
perf counters and tools to utilize in this endeavor.
If you can be more specific than "performance goes down", maybe we can
offer up some advice.

When you say 60 concurrent users do you mean without any delay 60 threads or
60 reasonable simulated users? What is the script doing?

I'm not sure of the testing tool being used, but the tester says 60
concurrent simulated users. The script is logging in, searching the catalog,
viewing PDF files, etc. From what I understand is a wide mix of typical user
functions.

The key here is what those 60 threads are doing. If there are standard user
delays for each of the scripts, you have a problem. If they're running
without any normal user delays you may need to be concerned but it's not
probably a problem.
