I recently tracked down a performance problem in our memcached setup, whose source was the 50 item depth search that occurs in item_alloc. I was pleased to see this fixed in 1.4.10<http://code.google.com/p/memcached/wiki/ReleaseNotes1410>, and we will be upgrading past this version soon.
Because this wiki page<http://code.google.com/p/memcached/wiki/DevelopmentRepos> says that active development is happening in the engine-pu branch and the depth search is still present in this branch, I was worried this performance problem would find it's way back into the main branch, so I've made an attempt to patch it. I now see that there hasn't been much recent activity on the engine-pu branch. Is that still the correct place to look for active development? Maybe this has been fixed somewhere else I'm not looking? Anyway heres my diff if anybody is curious: https://github.com/joshtabak/memcached/commit/726dc155ee9202b738c4bf564a9a75367993b042
