David,
Thank you for the helpful response sir. I've browsed through the Server
Stats page in Webtools before, but never dug into it. What a great tool
with lots of detailed info.
Looks like we'll be moving the DB to it's own server so we can bump up the
thread count without slowing the server to a crawl during peak periods.
Thank you sir!

Subject: Re: [OFBiz] Users - Handling increased traffic
If everything is "tuned" properly the server should scale linearly in
the range it is tuned for. In other words, no matter the load with
twice the traffic the response times should double and no more.
In any setup there will be an effective traffic range and at the top
end of that range the response times will no longer scale linearly.
That is the point you want to focus on, ie when the load ceases to
scale linearly.
On a live server you can use the ServerHitBin to identify these
points by looking at the traffic versus response time for different
periods.
The trick with this is to see which resource is not scaling linearly.
If it is scaling linearly throughout, you need more hardware to
handle the load. If it is scaling memory until it runs out of memory,
you can just add more memory to the server (this is a common non-
linear scaling point because hard-disk as memory is a LOT slower than
RAM). You can watch memory, processor and disk resources with various
tools (for Contegix servers they remotely monitor all of this and
send us alarm notices if/when something happens, and that's a good
way to go).
Beyond this it's a little hard to say without looking closer. There
is some general info in the Basic Production Setup Guide, and some
helpful info in the Configuration, Deployment, and Maintenance
outline (both of these are linked to from the Docs & Books page on
the ofbiz.org site).
Best of luck, and nice to hear from you again Sterling.
-David
