This is another impasse. Are there other factors that cause query buffer resize to slow down? We crawl Pstack again. But at this time, jemalloc aroused our attention. Recall the memory allocation mechanism of REDIS, R

. New versions of glibc present in RHEL6 include a new arena allocator design. In several clusters we've seen this new allocator cause huge amounts of the virtual memory to being used, since when multiple thrEADS perform allocations, they each get their own memory arena. On a 64-bit system, these arenas was 64M mappings, and the maximum number of arenas is 8 times the number of CORES

,"). Allocates memory from the global heap using the page's lock-free stack. Use another lock-free stack belonging to each thread to return the moving/"fickle" blocks to their original thread. The following is a more detailed algorithm. If you feel that the attached description above makes sense, you can skip here. Anyway, the last part of the "fickle block" is interesting: Each thread retains a "free doubly linked list" of fre

Placement New is a predefined, overloaded new operator that constructs objects directly on an already-requested memory, such as: point2w* PTW = new (Arena) Point2w;//arena is the address of the requested memoryArena points to a block of memory to place the resulting POINTW object. He needs two parameters, and the implementation is simple, and returns the address referred to in the pointer (

because the auto_ptr object cannot be explicitly reset to point to the second object unless the second auto_ptr is assigned. # Include # Include "account.

, so the new mechanism are more predictable.... Memory use isn't that much of a premium anymore and most of the memory pool doesn ' t actually require memory until it's U SED, only address space ... We have done internally some measurements of the effects of the new implementation and they can quite dramatic. New versions of glibc present in RHEL6 include a new arena Allocat or design.
