[Zope] performance tuning

[sean.upton@uniontrib.com]

My hunch would be that the reverse-proxy route is the best practice, for
reasons of scalability: if you ever move to a ZEO cluster, it is highly
likely that you want to put multiple ZServer instances as ZEO clients behind
Squid (perhaps mod_proxy can do some sort of round-robin as well); you need
a load-balancing proxy to do this.  If this doesn't sell you, if you run
anything that even has some mix of dynamic, semi-dynamic, and static content
- this is 95% of sites - the caching aspect should.

Long ago, I thought about doing Squid->Apache->Zope, and then realized that
the latency of doing that much proxying is pointless (we now use Squid to
proxy/balance/cache multiple ZEO clients).  I can promise that, thanks to
Squid, an Apache-free setup with Zope is possible, and works quite nicely.

I doubt there'd be much difference (you can throw mod_proxy in the mix too).
Relative to Zope's overhead, I don't think it even matters. But, by all
means, go forth and test. I always love a good benchmark. Keep in mind that
you results probably won't translate to other OSs.

You might gain some real-world edge with mod_proxy which can do caching if
most of your content is static. I don't know if mod_rewrite or FastCGI will
help you do that.
