Set up tc_malloc to default on the whole system on Linux

You can use a faster memory allocator for multi-core CPU if you use Google's tcmalloc (https://github.com/google/tcmalloc).

At first install tcmalloc from your repository:

$ apt install libtcmalloc-minimal4

 Now ready for testing with Firefox:

$ LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libtcmalloc_minimal.so.4 firefox

If you like it, now you're ready to apply system wide:

$ cat /etc/ld.so.preload
/usr/lib/x86_64-linux-gnu/libtcmalloc_minimal.so.4


This is tested on Debian Bookworm and Linux Mint.

Do at your own risk! On this site I give the quick step without detailed description, benchmark and other things.

 

Have a nice day!
