Yes, a goal would be to known what kind of pages are most
requested. The individual path of each visitor is probably not worth
following, I think it's more important to check what kind of content
is requested and what could be potentially cached.

For example, ViewCVS can deliver both the latest version and old
versions of a document. If 90% of requests concern the latest version,
then we could think about caching it, and update the cache on CVS
commits. But if it's just 20% of requests this is probably not worth
it.

Stephan was also considering the setup of a reverse caching proxy -
would it worth it? That depends on whether the same pages are
frequently requested, or whether the requested pages are all very
different.

Eventually any stat that could show us how much the ViewVC service
weigh in the current Savannah load average. If we discovered that 80%
of the CPU is dedicated to the ViewVC service only, I guess we'd
consider switching to another CVS web browser, or disabling the
service, or in any case putting more effort in improving its
efficiency.

Cheers,
