Subject: [PATCH] Better kmalloc effeciency
Date: Mon, 04 Mar 2002 20:58:15 -0500 [thread overview]
Message-ID: <3C842637.5350F969@didntduck.org> (raw)
[-- Attachment #1: Type: text/plain, Size: 348 bytes --]
This patch adds two intermediate general cache sizes, 96 and 192 bytes.
On my system this saves about 34k.
size-256 63 180 256 5 12 1
size-192 95 120 192 5 6 1
size-128 213 240 128 8 8 1
size-96 1080 1120 96 28 28 1
