Hello all,
I've gone through and read most of the information posted from this list
about improving the performance of Orion, and increasing the number of
threads Orion uses to improve its overall performance under load.
What I've been able to do so far, and it's helped a lot, is:
1- Added the -Xms and -Xmx switches to make sure Orion starts and uses more
memory, they're set at 100MB and 300MB respectively, and Orion uses 175MB
as soon as I start it up, and doesn't seem to grow past 177MB as the day
goes one and it gets used.
2- I added the -server switch in front of the java command so we make sure
we use the Server version of the HotSpot VM. (Boy does this thing pick up
speed when using the -server switch!)
Is there anything else that can be done, short of clustering, to further
increase Orion's performance?
My main objective is to make sure we don't get any more weird hangs and
long wait times in Orion for no apparent reason. Perhaps increasing the
number of threads Orion uses? I can't seem to find any definite answer on
that.
Our servlet seems to be fine, but sometimes when clicking through a test
web site, one url request seemed to just sit there and hang, as if Orion
was dead, but I could click and request a different URL and get immediate
response. So I assumed it was threads in Orion which were not being
managed properly.
After making reading the posts to the list and making the the 2 changes
above, the problem seemed to have gone away for the most part, except it
still happens from time to time in Netscape, IE doesn't seem to have this
problem. I can quit Netscape and go back in and the problem is gone for a
while. There is no specific time frame for it to happen. It does happen
consistently when I click, then stop for about 30-60 seconds, then click
again or reload, and it just sits there and waits for the world to come to
an end of something. Very bizarre.
Any ideas you may have would be of great help.
Thanks
