Hello,
I sent this to amd64-list yesterday and received no response. I've
noticed different vendors use different BIOS defaults for the AMD64
ECC hardware scrubbing.
Tyan S2884 | Sun V40z (Newisys 4300)
-- ---- ---- ---- ---- ---- ---- --|-- ------
Dcache ECC Scrub Ctl Disabled | 5.12us
L2 ECC Scrub Ctl Disabled | 10.2us
Dram ECC Scrub Ctl 1.3ms | 163.8us
Has anyone on this list experimented with how these values affect
application and OS performance on RHEL 3 AMD64? We've seen blackbox
servers running the Tyan motherboard outperform Tier 1 vendor Quad
Opteron machines and I wonder how much these settings have to do with
it. Thanks for any info.
/Brian/
