Well, not here but it does seem to have fallen back one or more days. I'm also curious about the zope.org site performance. Zope is said to capable of a million hits per day on commodity hardware, yet zope.org receives only about 20% of that on its busiest days. This would not be remarkable except that the response times from zope.org seem to usually be 10 seconds or so. I am on a T-1 line and 13 hops and 80ms from the zope.org server. -- Dennis Nichols nichols@tradingconnections.com

I just sent a message explaining what happened to this list.

My current tracking shows that zope.org is pretty snappy until the server gets attacked from a bunch of spiders. Because zope.org has a huge quantity of pages (500+MB of (packed) content and climbing), and because objects get loaded into ram as they get accessed, accessing *everything* on the site multiple times causes zope to load things in & out a lot, causing it to slow down. IOW, if you have a zope running with, say, 100 mb of content (that's 2048 50 kb pages) on a box with, say 256mb of ram, and you have your caching policy set very liberally, then you should be able to hit 30 requests per second, or 2.5 million hits per day. Zope.org will be on hardware that stretches the notion of "commodity" soon, but it will be sufficient such that all 500mb of our objects can be floating about in ram if need be. This should improve our performance drastically. Hope that helps, -- -mindlace- Zopatista Community Liason
mindlace, Check out my company's new HOWTO on an additional way to improve performance: http://www.zope.org/Members/Mamey/mod_gzip On Wed, Nov 01, 2000 at 11:38:42AM -0500, ethan mindlace fremen wrote:

Just did a quick check. < 5s for a home page reload over a 45k dial-up connecting from the UK. I don't notice any obvious lags using a permanent connection from work, apart from when doing searches, which is fair enough. Richard
