Ruby crawling on a Win2003 Server

ruby-talk
1

I have an application that makes heavy use of ActiveRecord to fetch data and publish to files. When running on my local machine (a laptop with WinXP) I produce 1-2 files per second which is perfectly acceptable. When running in the production environment (a Windows 2003 server with double processors and mucho memory) it crawls. It takes about 30 seconds to produce each file (using the same dataset although running on different db servers (localhost (which is contextual...) MySQL 4.1.x in both cases)).

Is there anyone who has any idea of what might be going on? Any profiling tips for a Ruby noob?

Ruby 1.8.2 is used.

Thanks

Try looking at the Windows Event Viewer first in Computer Management.

I'd try to profile with PerfMon as well as Ruby's profiler. For databases
often IO is the bottleneck, so if your 2003 server is slow then maybe it's
doing something else. Online virus scanners often also have an adversary
effect on performance... HTH

Kind regards

Okay. I'll look into this. Thanks.
