Subject: Re: [PATCH] mm: add ztree - new allocator for use via zpool API
Date: Thu, 16 Sep 2021 11:33:40 +0200 [thread overview]
Message-ID: <CAM4kBBKmz76R11yu1H1BfgO0XLXT2SeZviuHUAnjVRo-vYVYKQ@mail.gmail.com> (raw)
> ztree is a versatile backend for zswap and potentially zram. It got its name
> due to the usage of red-black trees to store blocks of compressed objects.
> These blocks consist of several consecutive pages and ztree keeps an integer
> number of objects per block.
>
> For zram, ztree has better worst case malloc() and free() times than zsmalloc,
> does not deteriorate over time and has slightly worse but comparable compression
> ratio. For zswap, ztree has better worst case malloc() and free() times than
> z3fold, better compression ratio than z3fold and supports reclaim unlike zsmalloc.
