jemalloctcmallocptmalloc3hoardnedmalloc五种内存管理器方案 malloc内存分配,这里的存储分配程序,讲的就是标准库中malloc函数的实现原理。首先要了解针对malloc的内存存储结构。malloc不像全局变量一样,不是在编译器编译的时候就会分配内存空间,而是在调用到malloc函数
在100个线程并发的情况下,nedmalloc的平均分配速度比tcmalloc快约20%,比jemalloc快约15%。 当线程数量增加到500时,nedmalloc的性能优势更加显著,其吞吐量比tcmalloc高出近30%,比jemalloc高出约25%。 在延迟方面,nedmalloc的表现同样出色。在相同的测试条件下,nedmalloc的99th百分位延迟仅为tcmalloc的一半左右,比jemal...
There are many similarities between the designs, and like nedmalloc jemalloc keeps changing its internals over time so whatever I say here is likely out of date! Last time I looked, jemalloc uses red-black trees internally which are considerably slower than binary bitwise trees. On the other ...
