I think tcmalloc will output protos too now which google pprof tool understands. If you’re using standard glibc malloc you’re probably leaving a lot of performance on the table

Performance wise it doesn't matter for most projects like games where allocations aren't done in hot paths anyway.

Problem with tcmalloc is fragmentation. Luckily I can then on aggressive decommit in some scenarios and that helps.
