Apologies if I don't really feel like going through this again: can you search the mailing list history for threads started by me, discussing the last few releases? It talks about the performance you'd expect. Not having any threads and running each daemon individually will be "faster overall", but thread scalability in 1.4.15 is pretty good (11-12 cores just fine) and allows much higher efficiency of multiget, simpler management, less memory wasted on tcp connections, etc. If you run one instance per numa-node you get sort of both worlds right now. Solarflare even posted an article recently on tuning it that's pretty good. Please do your research. -- --- You received this message because you are subscribed to the Google Groups "memcached" group.
