mod_gizp is not a panacea. Content gzipping/deflating is turned off in 
many-many cases. AFAIK, all proxies, including squid, requests 
uncompressed documents. So if you sitting behind a proxy, you can't get 
any benefit from enabled mod_gzip. And i'm almost sure that this works 
in the same way if you use Squid (and possible Apache) as a Zope 
front-end. Also, as i remember, Apache's mod_gzip turns itself off in 
many cases (some browsers have bugs in decompressor implementation, 
etc). I think this is covered in more details in mod_gzip docs.

Some time ago i was playing with Apache's mod_gzip on one of my 
plain-html (non-zope) sites. Both original and gzipped sizes was written 
to logs. And the overall benefit was rather tiny - a few percent, as i 
remember.
