If the problem is network latency, you could try setting SendBufferSize to a
large value, like 
32768, 65536, or even 131072.

   http://httpd.apache.org/docs/2.2/mod/mpm_common.html#sendbuffersize

This will increase the memory required for every request, so you won't want
to make it any larger 
than is necessary.
