This misses one point - with a pre-forking httpd, and dynamic content
generated with buried interpreters and pre-byte compiled modules,
such as php or modperl, an accelerator allows the child httpd to
write at full speed then become free for another request. With
modperl this is absolutely critical given that one httpd can easily
exceed 10mb of non-shared memory.

Which brings up a question.. will squid buffer non cacheable dynamic
content of any length and feed it to a slow reader? or is there a
limit (8k, 16k?) that would delay the accelerated httpd from
finishing the request at full speed.
