编译安装

unzip tcmalloc.zip
tar -zxvf gperftools-2.1.tar.gz
cd gperftools-2.1
./configure --disable-cpu-profiler  --disable-heap-profiler --disable-heap-checker  --disable-debugalloc --enable-minimal
make -j4 
make install

执行完以后，看一下结果

使其生效

在/etc/profile 最后添加一行

export LD_PRELOAD=/usr/local/lib/libtcmalloc.so

然后reboot 重启系统。

验证成果

重启后查看是否生效。 可以看到已经生效。
