Subject: [PATCHv2 4/4] zsmalloc: set default zspage chain size to 8
Date: Mon, 9 Jan 2023 12:38:38 +0900 [thread overview]
Message-ID: <20230109033838.2779902-5-senozhatsky@chromium.org> (raw)
In-Reply-To: <20230109033838.2779902-1-senozhatsky@chromium.org>
This changes key characteristics (pages per-zspage and objects
per-zspage) of a number of size classes which in results in
different pool configuration. With zspage chain size of 8 we
have more size clases clusters (123) and higher huge size class
watermark (3632 bytes).
Please read zsmalloc documentation for more details.
