I've never heard of putting squid _between_ apache and ZServer, but why not put squid on the outside of your system as to not create extra latency?
Ive measured latency at moderate loads... for cache misses the difference is negligible, largely because Zope has a relatively high latency. If you have some pages that are: * uncacheable, and * latency-critical then you could use mod_rewrite to send them directly to Zope (not via squid). The advantages (for me) of putting Apache on the outside are virtual hosting, and using mod_rewrite to pull other back-end servers into Zope's URL namespace.
I think squid is much more advanced than mod_proxy in terms of caching options and raw speed. I am currently setting up a ZEO cluster with nodes running ZServer sitting behind a pair of load-balanced squid caches
Interesting. Are you planning these two Squid's to be independant, or peers? Toby Dickenson tdickenson@geminidataloggers.com
