         fastcgi_buffers 64 64k;
         fastcgi_buffer_size 64k;

i made the following mods in the fastcgi section, and waiting for 
results. from what i understand:

         fastcgi_buffers 64 64k;

the first 64 is the number of buffers and the second is the buffer size, 
so on a server that takes around 500 hits per second should i increase 
it, or the value should be just fine ?
