Tcmalloc
|
|
========
|
|
|
|
'tcmalloc' is a library Google created as part of the google-perftools
|
|
suite for improving memory handling in a threaded program. It's very
|
|
simple to use and does work fine with Suricata. It leads to minor
|
|
speed ups and also reduces memory usage quite a bit.
|
