Provide a way to bench memory allocators

[jvoisin]

Mimalloc-bench would like to make use of fleetbench, but unfortunately, it seems that the usage of tcmalloc is hardcoded into the binaries. Would it be possible to make it optional, since mimalloc-bench is using LD_PRELOAD to override malloc/free/….

Hi @jvoisin,

Fleetbench is built with Bazel, which supports --custom_malloc option (bazel docs). This should allow you to override the malloc attributed configured to take tcmalloc as the default. Could you please try this and let us know?

Hi @jvoisin and @aysylu ,
Are you able to run fleetbench with other allocators (other than tcmalloc and system/glibc) ?

I haven't tried :/
