Arjun Shankar 2019-11-26 18:01:21 UTC Doc Text Feature: The malloc function uses a series of "fast bins" which hold re-usable chunks up to a specific size. The default maximum chunk size held this way is 80 bytes on 32-bit systems and 160 bytes on 64-bit systems. This includes malloc's internal overhead of 4 bytes on 32-bit systems and 8 bytes on 64-bit systems. This update adds a new glibc tunable, "glibc.malloc.mxfast", which can be used to alter the maximum fast bin size.

Reason: Applications which value reduced memory footprint over speed may choose to reduce the size of requests which are serviced from fast bins by adjusting this tunable.

.The new `glibc.malloc.mxfast` tunable is available for `glibc

With this enhancement, a new `glibc.malloc.mxfast` tunable is added to `glibc`. With this tunable you can change the maximum fastbin size.
