Using ie, webrieck ( all on win xp) and rails-0.13.1  
I find that I get very very slow response when using ajax to update a  
form.  
Much slower than a regular page load. So bad I have considered dropping  
ajx  
completely  
In my production env I use apache/fcgi and it is instantaneous  
Any suggestions? ( apart from use fcgi in dev!)  
Thanks  
Paul

I think 0.13.1 was leaking memory in development mode. That might be  
the source of your troubles. Can you upgrade?

Webrick only runs one thread, so things like file-uploads and ajax  
will suffer from low throughput.

## Unfortunately, no, not really. You’ll either need to investigate scgi/fcgi for development, or just live with the slow requests.

Cheers

ok, thanks. I can try an upgrade. I did also use apache/fcgi -but I had  
to  
stop, and if I remember it was because I had to restart apache to get  
updated content - does that sound correct?
