Subject: PAE/NX without performance drain?
Date: Sat, 09 Dec 2006 15:39:30 -0500 [thread overview]
Message-ID: <457B1F02.7030409@comcast.net> (raw)

Hash: SHA1
Apparently (as I've been told today) using a hardware NX bit in a 32-bit
x86 kernel requires PAE mode. PAE mode is enabled with HIGHMEM64, which
is (apparently) extremely slow.
Is it possible to give some other way to get the hardware NX bit working
in 32-bit mode, without the apparently massive performance penalty of
HIGHMEM64?
