Enables redis to use tcmalloc to implement high-performance nosql servers

Tcmalloc (thread-caching malloc) is a member of Google-perftools, an open-source tool developed by Google. Compared with the standard glibc library's malloc, tcmalloc has much higher efficiency and speed in memory allocation, which can greatly improve the performance of the MySQL server in high concurrency, reduce system load.

Installation Steps of the tcmalloc Library (in Linux ):
Step 1. Install the libunwind Library first for the 64-bit Operating System(Do not install the 32-bit operating system)
The libunwind library is based on 64-bit CPU and Operating SystemProgramProvides the basic stack trigger and undo functions, including the APIs used to output stack traces, APIs used to program the trigger and undo stacks, and APIs that support the C ++ exception handling mechanism.

Step 2. Install Google-perftools:

So. conf. d / Usr_local_lib.conf # If this file is not available, create one by yourself Sudo / Sbin / Ldconfig

Step 3. Install redis

$ curl -O HTTP: / redis.googlecode.com / files / redis-2.2.12.tar.gz $ tar xzvf redis-2.2.12.tar.gz $ Cd redis-2.2.12 $ make use_tcmalloc = Yes $ sudo make install

Step 4. Check whether tcmalloc takes effect

Step 5. Test redis
