Subject: Benchmarking objrmap under memory pressure
Date: Tue, 13 Apr 2004 00:39:41 -0700 [thread overview]
Message-ID: <1130000.1081841981@[10.10.2.4]> (raw)
UP Athlon 2100+ with 512Mb of RAM. Rebooted clean before each test
then did "make clean; make vmlinux; make clean". Then I timed a
"make -j 256 vmlinux" to get some testing under mem pressure.
I was trying to test the overhead of objrmap under memory pressure,
but it seems it's actually distinctly negative overhead - rather pleasing
really ;-)
