I've mentioned at the beginning of this article, that we already have several systems running with tcmalloc. So using jemalloc would mean that we would need to bring new dependency. Tcmalloc solves fragmentation issue really well for us, we can get estimation of how much memory is 'lost' due to fragmentation. We saw that potential saving from let's say jemalloc, cannot be higher than 1-3% of memory use and decided it's not worth to bring new dependency for so little value.
