Request notifications

Posted by Gustaf Neumann on runs since two days on OpenACS 5.9.0. One of the benefits of OpenACS 5.9.0 are the reduced number of mutex locks during normal operations. The following values are from day averages on days with similar loads:
Mutex Locks/sec      5.8.1   5.9.0
Total                  606     331
util memoize            57      14
xo_sitenodes            38      27 is a low traffic site, for which these improvements are not relevant. On the production site of Learn@WU we observed of the 50k locks/sec in total during the last year, and more than 6000 locks on the util-memoize cache per seconds. Reducing theses improves scalability.
