FCGI and Apache2 on win performance problem

Rails
1

Hi all,
I am having problems with FCGI and Apache2 on windows.
The error I often receive is 500 error code response with logs listed
down. I successfully use Webrick server and CGI (very slow). I had
configured apache as is described in these document:
http://dema.ruby.com.br/articles/2005/08/23/taming-fastcgi-apache2-on-windows.

Any suggestions?

Logs:

I am running into the same sort of intermittent errors. Wondering if
there could be a but in the active record gem mysql adaptor with a dual
CPU machine. Is your machine a dual?

If I repeatedly reload a page that does no database access, it never
fails. However, the moment I do foo = MyTable.find(:first), I can get
it to fail pretty quickly. I have tried using both MySQL 4.1 and MySQL5

Actually, though, in addition to FCGI not working the way you describe,
I also see crashes with WebBrick on this machine. It never crashes on
my development machine (Mac). Unfortunately, I have to deploy on
windows.

Ray, no it is not dual machine and I didn’t have any problems when used
Apache CGI or WebRick.

best,

A fix for a WEBrick concurrency issue was just checked into the trunk.
http://dev.rubyonrails.org/changeset/3454

This is probably worse on a dual CPU machine. Doesn’t affect FCGI
though.
