greg-b-roberts Our wiki hosted on windows 2008 r2 gets delays in rendering pages on occasions. Up to 30s but once a page is rendered the redisplay is quick. Now the issue may be in IIS7, i would like to know what trace features are available in the PHP app or php scripts to try to resolve the issue. Even if you discount caching expiring, it is hard to see how a 3GHz server can take 30s to render a page from scratch. Any helpful hints appreciated.
