Hi @bryancall I have 2 builds of traffic_server binary ready, one is the standard one packaged with Debian 11, but I do not know if it is built with jemalloc support. Is there any document I can refer to for building debs/binaries for Debian? I also have a custom compiled from source version of the traffic_server binary. I have libjemalloc2 installed on the server. For enabling the usage of jemalloc - do I need to disable Freelist as you've mentioned in your post? Should that be enough or do I need to specify to trafficserver anywhere that I want jemalloc to be used instead of the system's default `malloc()` and `free`? One of the posts I've found suggests an `LD_PRELOAD` of the library when running a program where you want to use jemalloc, So I've gone ahead and modified the systemctl file to include the Environment variable to preload jemalloc like so - ``` # # Licensed to the Apache Software Foundation (ASF) under one # or more contributor license agreements.

Or do I need to add something to `/etc/default/trafficserver` as well to get Jemalloc enabled? Also, will the above preload (systemd unit file) function properly for the prebuilt Debian version or will it only work for my custom --with-jemalloc enabled build? -- This is an automated message from the Apache Git Service.
