| |
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 ;-)
