Hi Folks,

My hosting company has just informed me that the CF7 instance for a
site I maintain is using about 65% CPU at the moment (on a Solaris
machine).   The site uses quite a few frameworks - ModelGlue,
ColdSpring, Transfer and Javaloader.

We have recently attempted to move this to CF8 but aborted the attempt
because it basically just ground the server to a halt.  So I think
there is something more sinister going on here that I need to sort out
before we attempt that again.

However I'm a bit stuck with where to go from here.  The site has been
going along quite nicely until recently.  Traffic has grown quite a
lot in the last 1-2 years which I'm sure is not unrelated. Just to
throw a few extra spanners into the works I *believe* this is a shared
server but I have no information on what else is running on it and
whether that could possibly be causing us problems.

I know this is very very vague but I don't get a lot of info from our
hosting provider except that we are using up too many resources.
Perhaps we have just outgrown our current hardware, but I am not sure
how to confirm this.  Any suggestions on what I could start looking at
to track down the source of the issues would be hugely appreciated.

Andrew.

P.S.  I do have a development server which is identical except that it
only has 2GB RAM as opposed to the 4GB in production.  Load testing on
this is definitely an option - I have used JMeter in the past but not
sure I have used it optimally.  Anyone got any suggestions on load/
stress testing tools?
