I maintain two WebObjects installation in China.
One of them is giving me problems - performance is slow. Our users
can't get connected, yet there are many sessions and much activity
in the logs.
I have 80 instances for 2 servers, they handle 10-30 sessions each.
Requests are completed usually in less the 1 second.
- Maximum Adaptor Threads is 512
Increasing this correlates to increasing incoming connections to
the HTTP server.
- Listen Queue is 2
It was 10, I don't want too many people in the queue to start any
sessions when the user ends up quitting and trying again -
therefore ending up with two sessions were one is left to timeout.
- Session timeout is 10 minutes
For Adaptor settings:
- I'm using Load Average to balance the load.
- Send timeout is 10 seconds.
- Receive timeout is 600 seconds since we may execute queries that
take some time, very rare.
- Connect timeout is 10 seconds.
- Connection Pool is 2
I might get 300-400 concurrent connections to the web server. I
should be able to handle that.
The WO servers never see high CPU load and have 25% inactive RAM
available.
On the database server, there is no sustained high CPU load.
I'm using InnoDB. My ibdata file is 20GB - I assume this to be very
large.
To me these numbers are contradictory but these are the numbers.
Any thoughts? Anything that blatantly wrong with this?
Thanks
