Hello,

First of all I need to emphasize the fact that I know WHeezy is not yet  
supported.  
What I am trying to determine how WHeezy could impact Nginx (compiled  
for  
Squeeze) performance.

Since I made the upgrade, big files are being served in a slow fashion  
(~200 kiB/s).  
The directory serving them is configured with AIO and worked perfectly  
before system changes.

I know Sergey listed some changes in the  
dependencies[http://mailman.nginx.org/mailman/listinfo/nginx](http://mailman.nginx.org/mailman/listinfo/nginx),  
but what precisely would explain such a slow-down?  
Is there a defect somewhere that I can work on or just be patient and  
wait  
for the release of the Wheezy build of Nginx?

## Thanks,

_B. R._

Packages for wheezy and raring have been uploaded.

I see no performance degradation in test with aio enabled on VM with  
wheezy in comparison  
with VM with squeeze.

Thanks for the work on Wheezy ;o)

Thanks also for the performance tests. I’ll look into it.
