Package: gcc Version : gcc (Debian 4.9.2-10) 4.9.2 or gcc (Debian 4.7.4-3) 4.7.4
when we use tcmalloc lib to malloc memory, we use gcc (Debian 4.7.4-3) 4.7.4 compiling the gperftools (version 2.1) and use gcc (Debian 4.9.2-10) 4.9.2 compiling the same version gperftools, running on jessie (version 8.2) . we can see the tcmalloc used gcc 4.9.2 get a very higher latency(more than 10 times) than tcmalloc with gcc 4.7.4-3. we use tcmalloc lib with gcc 4.7.4-3 instead of tcmalloc lib with gcc 4.9.2 , the problem is solved. The code is the same, why gcc 4.9.2-10 version is higher than gcc 4.7.4-3 ,but get the more latency ? if u need any more infor pls tell me . BRs Yongsu
