First, i've started using rewrite rules as i find it far more flexible. For Zope.org, in lieu of ProxyPass ProxyPassReverse I just use: RewriteRule / http://www.zope.org: [L,P] If you've got the SiteAccess set up correctly (i.e. it reads http://xxx.xxx.xxx/paginas/ ) then you should have no problems. ProxyPassReverse is, as far as I can discern from the apache docs, completely superfluous for Zope.

Re: [Zope] Zope is very slow!
Why do you see any need to turn ProxyRequests On? I run the ProxyPass too, but there is no need for the ProxyRequest and the Proxy module.

Re: [Zope] Zope is very slow!
Hi Christiano (nice first message... :) ) First of all, lets define slow. What does slow mean? Have you tested it with AB (apachebench)? You sure it is not your connection? Watched it in TOP? My guess is that with 2.1.6 (straight) on that system you should be able to get about 200 requests per second which is not SLOW at all. Check your Apache, Proxycache and SiteAccess my guess it is there. Turn off debugging. Upgrade to 2.2.1 (60% faster on dual processors). Take a look at http://www.zope.org/Members/BwanaZulia/benchmarks.html to get an idea of what you system should be doing. Just some suggestions.

Upgrade to 2.2.1 (60% faster on dual processors). Really? I didnt see anything about this in the Changes file... has something else changed I didnt see?

Re: [Zope] Zope is very slow!
I am pretty sure (61%) that in the original release of 2.2.0 there was something about a speed increase. One talked about on single processor (20-40%) and the other was dual processor (60-80%). It partly has to do with that "one line of magic code" in the z2.py. Ethan? Paul? DC? Care to shed some light?

It partly has to do with that "one line of magic code" in the z2.py. Ethan? Paul? DC? Care to shed some light? The speedup involves changing sys.checkinterval, which controls the interval (# of bytecodes) at which the Python runtime performs certain housekeeping chores. For multithreaded programs, upping this interval can cause a significant performance improvement (more about this on python.org in the sys module docs). 2.2 sets the interval to 120, a value that seemed to provide a general speedup across a number of systems I tested. Granted, this is not very scientific, which is why there is an '-i' option to z2.py that allows you to pass your own values for the interval to experiment and find a sweet spot for your given environment (see the z2.py docstring / command help). else changed I didnt see? I noticed that 2.1.6 wasnt making the best use of dual processors. I thought only ZEO would make good use fo dual processors? Note that effective use of multiple processors is mostly a function of the Python runtime (specifically the global interpreter lock) rather than an issue that Zope can address directly. So yes, ZEO is the best way to make effective use of MP.

Re: [Zope] Zope is very slow!
I have limited experience with ProxyPass. I have many Zope installations (2.1.4, 2.1.6, 2.2.0b2, 2.2.0) on all sorts of different hardware configurations (all RH Linux) and non of them are slow. Most are running just plain ZServer but one (and the most hit) is running behind Apache with Zope.cgi. I suggest trying that and seeing if it makes a difference.
