Subject: [9fans] map and unmap pages of memory
Date: Wed, 18 Nov 1998 18:28:45 -0500 [thread overview]
Message-ID: <19981118232845.eHy8SPe7i-NkU2FFY42F0KGo6HqvOoHm8qwxAj5mXcQ@z> (raw)
That test from hBench-OS is measuring the speed of the
memory-mapped file calls, which don't exist in Plan 9.
The necessary hooks are there and are being used to
load executable images -- a long time ago I
thought about proposing an extension to segattach
to accept "file!n" where n is an open file descriptor
as at least a read-only mmap.
I'ld be interested to hear what numbers you got
out of hBench under Plan 9 on a particular machine as compared
with that same exact machine running say Linux or one of
the BSDs.
Russ
