It is running Apache 1.3.4 through PCGI to ZServer running with six Zope threads. It currently gets approx 50,000 hits per day. The ZODB size, packed, is 150+ MB and slowly growing. There is nothing really special about this hardware, just a straight up intel box with a SCSI drive and 256MB of memory. The machine is hosted in Los Angeles, CA by Codeit computing on a 10Mbit ethernet. The load average, right at this moment, is 6.28 (ouch!) The machine serves as our web server, mail server, mail-list server (which sends over a hundred messages to over a thousand people a day, you do the math), and demo server. We are right now in discussion with a major linux hardware vendor about getting a couple big boxes to take the strain. The upshot of all this is that Zope has been running beautifully on the zope site under this huge strain; this is real world testing in action. No one anticipiated the massive surge in resources that happened over the past three months. In June, we had 500K hits per month, in August, 1.1M. This month looks like it's going to break all the records. -Michel

Hi I was trying to run ZServer with pcgi .. details first... on : solaris 2.5 zope ver: 2.0.1 python ver: 1.5.2 intending to use zope with apache 1.3.6.... I used python z2.py -p . the error I got is... Traceback (innermost last): File "z2.py", line 463, in ? logger_object=lg) File "/home/Zope-2.0.1-src/ZServer/PCGIServer.py", line 282, in __init__ self.read_info(pcgi_file) File "/home/Zope-2.0.1-src/ZServer/PCGIServer.py", line 319, in read_info k,v=string.split(line,'=',1) ValueError: unpack list of wrong size can u help me with what the reason for this error could be??? and I 've changed HTTP_PORT to some other number cause i was already using 8080..it should'nt make a difference..should it vinod.

Zope.org performance
by Sean Treadway 18 Oct '99

18 Oct '99

Now, I am keen on Zope like nobody, but after going to www.zope.org Friday at about 10:00 US/EST the site would not respond any faster than 30 secs/hit?!? I was trying to convince somebody of the power of Zope and in return I got a very suspicious customer. Please, could someone give some load information about the main zope site? It is an excellent place for evangelizing Zope and giving a seat-of-the-pants demo, only if it is performing well. If the site's poor performance is explainable, then please, we want an explanation. If not, then what kind of options do we have if we plan to deploy Zope in a similar, as I see it now, medium sized web site and why aren't they used on www.zope.org? This has become somewhat of a FAQ. Are there any statistics about what kind of setup Zope.org is running? How many machines, pcgi or ZServer, how many hits/day, mean response time, ZODB size, is it using ZEO, etc.? Thanks, Sean

RE: [Zope] More Pystone benchmarks...

One of the reasons you are seeing much better Apache performance on your four-by than Zope is probably due to the Python global interpreter lock. Where multiple apache processes can run on all four processors with no interlocking, multiple zope threads running in the same process space all lock around the central python interpreter lock. While some IO operations and other things are done unlocked (like Zope DA communication, if the underying C library was written to release and acquire the lock) for the most part Zope can't get much advantage from a multi-processor system. This is one of the reasons behind ZEO. ZEO basicly breaks the thread model out into the multi-processor model, where the processes can be running locally or on seperate machines. On your four-by, for example, you could run 3 or 4 ZEO client processes and one ZEO server process. When your load fills up, you can simply plug more machines running ZEO clients into the ZEO server. No one has tested this scalablility yet because no-one has come to us with these kinds of load requirements. It will happen, in fact, some of our recent customers are gearing up for this kind of load. -Michel

Someone posted this link to SOAP on the Zope list earlier: http://msdn.microsoft.com/workshop/xml/general/soaptemplate.asp And here is the Microsoft SOAP IETF draft: http://msdn.microsoft.com/workshop/xml/general/SOAP_V09.asp > SO the point I'm trying to make is that Zope is a great name because it > is unique which means its really easy to remember and just about zero > chance of confusing it with anything else. SOAP would be the only thing to really confuse it with. Haven't heard much talk about SOAP interacting with XML-RPC in Zope, or how Zope might implement SOAP later. This confusion should generally help Zope, though, not hurt it. - Ian C. Blenke <icblenke(a)2c2.com> <ian(a)blenke.com>

www.zope.org's source?
by Marc-André Lafortune 18 Oct '99

18 Oct '99

You wondering: I know I can get the DTMl of just about any page of www.zope.org (very nice feature), but is it possible to access the whole site to look at the organization, modules, etc... ? Also, is it just me or the site is very slow (~3 seconds delay for most requests)? I just hope it isn't because of Zope itself, but what else could it be?

Question on: How-To: When Cookies won't do it
by Johan Carlsson 18 Oct '99

18 Oct '99

I browsed trough the How-To: When Cookies won't do it and I have some questions. How much speed do you really gain from using file for data marshaling? Would it be a good idea to use Object Pooling (pre created objects) to speed up a session object solution? The reason I don't like the file based solution is that I won't scale with ZEO but a Object solution would, right? There would also be possible for cool stuff like session failover and long time session (much list version but individual and perhaps with a limited scoop) Another reason is that I like the concept of the ZODB, why think in a non ZODB way?

As the guy who wrote this "lame argument", let me point out that if you'd read the whole piece, you'd have seen that I wasn't trying to make an argument at all, for or agains tanything. It's just a statement of fact. However, think about this. If you did not know of the name beforehand, and somebody told you (verbally) about Zope, what would you do? Would you go on the net and look for a www.zope.com? Would you try to find www.soap.com? www.zoap.com? Or would you respond, "Hmm. How do you spell that?" > Tad Murphy > "cybertad" > http://www.zope.org/Members/cybertad/ -- Alexander Staubo http://www.mop.no/~alex/ "`This must be Thursday,' said Arthur to himself, sinking low over his beer, `I never could get the hang of Thursdays.'" --Douglas Adams, _The Hitchhiker's Guide to the Galaxy_
