Subject: [plum] Plum under load?
Hi Adam and David -
I'm very interested in any information you can
provide about the performance implications of using the Plum framework under
very heavy load. At my new job, I may want to start convincing folks to
use Plum in certain instances, especially new development. I know
they're going to want to know how it performs under intense load (perhaps
eBay-type load within a few years, if everything goes well). We'll
really want to scale our applications (application, web, and database
clustering will most likely be involved). We would use some pretty
powerful app and DB servers, with a mix of Win 2K and Win 2003. The DB
will be SQL Server 2000. So...
1.) What kind of load testing have you done, with
what tools, with what hardware/software specs, and what were the
results?
2.) How do you suggest setting up Plum in a CF MX
6.1 clustered environment (possibly multiple machines, and probably multiple
instances of CF)?
3.) Normally, with a small cluster (2 or 3 app
servers), we would use Client variables with DB storage. So, would you
do this in a larger cluster under very high load? Perhaps we could use a
seperate DB machine just for Client session management?
4.) Are there performance implications with the
way Plum puts so many CFC's in the Application scope?
5.) I assume you would recommend switching as
many of the <CFQUERY> tags to Stored procedure calls? By the way,
one recommendation would be for an easier way to just make Plum use all sprocs
instead of inline <CFQUERY> code in the V1.1, as if you guys don't have
enough to do... :)
6.) Posting/documenting the results of
performance metrics for Plum under common configs with intense load would be
very helpful if anyone has the time and setup to do it.
7.) We might also move to CFMX 7 soon, so any
information on how Plum performs under load with 7 would be
helpful.
Thanks much!
Aaron
