Running Apache Bench against my blogs showed a modest improvement of 1 -
3% for most runs.  Larger numbers of requests and increasing concurrency
showed the most benefit.  When I really hammered the server, load
average was less with the cache turned on and the longest response time
was much shorter.

Please run benchmarks and see how it handles.  If the persistent cache
doesn't buy us much, we can consider turning persistence off by default.
(By persistence I mean saving the objects to disk.  We always cache in
memory.  Even without saving to disk, there is a cache and it is hit
hundreds of times for each page load.)

Even if the persistent cache doesn't dramatically increase performance
for most, the code and API cleanup that resulted from adding it are
worthwhile.  It's not much more code than before, it's all in one place,
it degrades nicely when persistence is disabled, and it's completely
pluggable.

Regardless, users shouldn't care about the cache.
