[Mono-list] ASP.Net Page taking minimum 11 sec to load first time

[Mike Cleaver]

I agree that the performance is fine once compiled, and its not a  
major concern in a production environment where batch compilation  
works.  Unfortunately I have two issues at the moment -

1) Batch compilation is not running from my site, maybe i have  
configured that in my web.config, im not sure. Will look into it today.

2) On osx, when i modify an aspx file, it is not recompiled so I have  
to restart xsp2 to see my changes.  I have put a little effort into  
checking if this is a known bug, if it isn't a known bug I'll submit a  
report for it but not sure how I'd present a test case.

I'm definitely going to look into batch compilation today, will post  
when I've enabled it..

Cheers,
Mike Cleaver
