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?!?
Note that ~10am is one of the peak usage times for internet bandwidth.
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?
The Zope site is currently under a huge strain due to the explosive popularity of Zope.
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.?
It is _one_ little trooper of a PII 350Mhz. 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.
Along these same lines I was also after a bit of help. Whilst my site is not get huge amounts of hits (yet :). I have been needing to suck the content from using wget. When I do however my system really starts to thrash badly and checking the top output I get this: <snip> MEM CPU% MEM% 30200 www-data 6 0 60328 56M 872 R 0 13.2 45.5 1:40 python 30212 www-data 0 0 60328 56M 872 S 0 0.0 45.5 0:00 python 30213 www-data 4 0 60328 56M 872 R 0 9.0 45.5 3:11 python 30214 www-data 1 0 60328 56M 872 S 0 10.4 45.5 3:09 python 30215 www-data 8 0 60328 56M 872 R 0 18.7 45.5 3:01 python 30216 www-data 10 0 60328 56M 872 R 0 19.1 45.5 3:14 python <snip> My site is only medium size (~200 pages, 16MB), however as you see it seems to use a fiar bit of memory, is it normal for it to use so much memory even thought my data.fs is 16mb (packed). The machine specs are: PIII450, 128MB, IDE HDD Any comments would be grateful, since I was planning on using Zope in a much heavier load environment in the future. Regards, Ben Leslie
