New page

[https://github.com/microsoft/mimalloc Mimalloc] is a drop-in replacement for malloc and can be used in other programs without code changes, for example, on dynamically linked ELF-based systems.

== Installation ==

To use mimalloc, ensure {{pkg|mimalloc}} package is installed on your Alpine Linux system:{{Cmd|# apk add {{pkg|mimalloc}}}}

== Configuration ==

To minimize risks while leveraging mimalloc, consider Per-Application Preloading:

=== Using mimalloc per-application ===

Preload libmimalloc.so only for specific applications by issuing the following command:{{Cmd|LD_PRELOAD{{=}}/usr/lib/libmimalloc.so my-application}}

If preloading fails or causes issues, you can unset it temporarily:{{Cmd|unset LD_PRELOAD}}

To use mimalloc for firefox:{{Cmd|LD_PRELOAD{{=}}/usr/lib/libmimalloc.so firefox}}

=== Using mimalloc systemwide ===

{{Note|Using mimalloc systemwide is not recommeneded as this is not guranteed to work for all applications. Test your critical applications using [[#Using mimalloc per-application|per-application]] before deploying it systemwide}}

To preload libmimalloc.so systemwide, set the LD_PRELOAD environment variable globally by adding the line {{Codeline|export LD_PRELOAD{{=}}/usr/lib/libmimalloc.so}} to the global shell configuration file {{Path|/etc/profile}} as follows: {{Cat|/etc/profile|<nowiki>export PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

# Set LD_PRELOAD to use mimalloc globally
export LD_PRELOAD=/usr/lib/libmimalloc.so

export PAGER=less
umask 022
...</nowiki>}}
