Oh, thank you for this link! No I never tested it but I've read their README and it looks super appealing, precisely because their main focus is worst case latency. While jemalloc performs super fast (which is also reflected in their benchmarks), we've got a few reports of some extremely long free() operations trying to purge too many objects and taking more than one second, which is absolutely not acceptable. The MIT license even allows to easily embed it into existing projects, though contrary to the venerable old dlmalloc, it's no longer a single file at all, and the code is a bit dirty with inconsistent coding styles between functions clearly coming from different contributors, so I suspect it could easily trigger warnings if built with the project's main files and build options. I'm also seeing that it requires special build options for valgrind and ASAN. I'll ping the few heavy users who experienced watchdogs in free(), in case they want to give it a try. Thank you! Willy
