HeapProfileStop() (5)之后进程会在每次申请内存超过1G或者减少内存超过1G的时候打印堆的信息(Linux包括虚拟内存的变化) (6)进程运行过程会在/tmp/目录下生成一系列的以 .heap结束的堆文件,分析文件,需要用gperftools目录下自带的pprof工具,命令行如下: pprof --dot …/server /tmp/profile.0001.heap > tmp.dot...
1. 静态dump方法：直接定义一个环境变量HEAPPROFILE 来指定dump profile文件的位置，如：/tmp/test.log,它将会在/tmp/目录下生成很多类似/tmp/test.log.0003.heap文件名的文件 env HEAPPROFILE="/tmp/test.log" /test/testprog 2. 动态dump方法：我们可以调用Google Heap Profiler的API来控制...
简单来说, 就是先preload上tcmalloc, 日常用用没啥问题, 当感觉出现问题时, gdb attach 上, 然后执行 call HeapProfilerStart("xxx") , 过一段时间, 再执行call HeapProfilerStop, 产出相应的profile文件, 然后detach出进程 以下为一些未整理的 link https://gperftools.github.io/gperftools/heapprofile.html...

Profile-Tuned Heap AccessTo motivate this work, we provide an evaluation of the differences between heapbased and nonheap-based accesses. We show that by using a procedure-stack-based predictor as the input to the allocator, we can achieve speedups of up to 5.5%.DavidKaeli...
