Has anyone done any throughput/benchmarks for the various new patches/code?
The block allocator stuff is fresh from the oven and still warm inside. I'll be posting benchmarks for it as the week goes on.
Something interesitng: I have 8 dell 2650's (dual xeon 2.8ghz+hyperthreading) and i've setup the one machine above with the patches.. All 8 machines are incoming MX/smtp machines which handle quite large loads (5gigs of mail per day).
machine 1: (mounted:noatime,nodiratime,data=ordered,alloc=skip_busy:dirid_groups,packing_groups)
21:16:17 up 12:17, 1 user, load average: 0.45, 1.04, 1.07
375 processes: 374 sleeping, 1 running, 0 zombie, 0 stopped
CPU states: cpu user nice system irq softirq iowait idle
total 7.2% 0.0% 32.4% 0.0% 0.8% 5.2% 353.2%
cpu00 1.8% 0.0% 10.6% 0.1% 0.9% 1.3% 85.0%
cpu01 1.5% 0.0% 7.4% 0.0% 0.1% 0.9% 89.9%
cpu02 1.7% 0.0% 7.0% 0.0% 0.1% 1.7% 89.3%
cpu03 1.8% 0.0% 7.4% 0.0% 0.1% 1.5% 88.9%Iowait total stays hovering at around the 6->8% mark..
machine 2->8: (mounted: noatime,nodiratime)
21:14:31 up 1 day, 8:41, 1 user, load average: 0.43, 0.72, 0.66
392 processes: 391 sleeping, 1 running, 0 zombie, 0 stopped
CPU states: cpu user nice system irq softirq iowait idle
total 8.0% 0.0% 35.2% 0.0% 1.6% 0.8% 352.8%
cpu00 2.0% 0.0% 11.1% 0.1% 1.5% 0.3% 84.6%
cpu01 2.0% 0.0% 7.7% 0.0% 0.3% 0.1% 89.5%
cpu02 2.2% 0.0% 7.7% 0.0% 0.0% 0.3% 89.5%
cpu03 1.8% 0.0% 8.7% 0.0% 0.0% 0.0% 89.3%The majority of the rest of the machines iowait hover around the 1% mark.. CPU time tends to be about the same, just the iowait is much much higher..
