this is the first release to feature the new threadpool.
- link to the documentation :
- link to preliminary benchmarks :
http://kb.askmonty.org/en/threadpool-benchmarks . NOTE: Axel ran his own
benchmarks recently too, and will probably blog/publish them soon. The
throughput curves will be similar as far as I can tell.
- I added some time ago to "What is new in 5.5"
Significantly improved for efficiency new thread pool , comparable in
functionality to the closed source feature in MySQL Enterprise
NOTE: pool-of-threads is now default scheduler on Windows Vista+ , so this
is a change our users should be aware of . I did not made it default on
Unixes (even if we had good benchmarks) yet, because Linux users are picky,
and Monty objected to do it just yet , and it had more own coding than
Windows case(where we rely on OS threadpooling functionality). So Unix
implementation should probably be better tested for corner cases in the
field, before it could be declared overall much better.
Can you add essence of the above to the release notes?
