Norman Maurer 8429ecfcc4 Implement Thread caches for pooled buffers to minimize conditions. This fixes [#2264] and [#808]. ... Motivation: Remove the synchronization bottleneck in PoolArena and so speed up things Modifications: This implementation uses kind of the same technics as outlined in the jemalloc paper and jemalloc blogpost https://www.facebook.com/notes/facebook-engineering/scalable-memory-allocation-using-jemalloc/480222803919. At the moment we only cache for "known" Threads (that powers EventExecutors) and not for others to keep the overhead minimal when need to free up unused buffers in the cache and free up cached buffers once the Thread completes. Here we use multi-level caches for tiny, small and normal allocations. Huge allocations are not cached at all to keep the memory usage at a sane level. All the different cache configurations can be adjusted via system properties or the constructor directly where it makes sense. Result: Less conditions as most allocations can be served by the cache itself		2014-03-20 09:30:57 -07:00
