Hi All, This is neto from Brazil How are you? I just need a help to make sure I understood correctly the report (see below --Output). Trying to generate 80% Read and 20% Write - 8KB block size Reads IOPS: 15330 Latency: (clat) 628usecs - 0.628ms Writes IOPS: 3827 Latency: (clat) 577usecs - 0.577ms Am I doing the correct analysis? One question is: Is it possible to have global IOPS and latency? All the best neto -- Config file (Windows) [workload] bs=8k ioengine=windowsaio iodepth=4 size=10g numjobs=3 direct=1 runtime=30 filename=\\.\PhysicalDrive1 filename=\\.\PhysicalDrive2 filename=\\.\PhysicalDrive3 filename=\\.\PhysicalDrive5 filename=\\.\PhysicalDrive6 filename=\\.\PhysicalDrive7 rw=randrw rwmixread=80 rwmixwrite=20 thread group_reporting -- Output workload: (groupid=0, jobs=3): err= 0: pid=2096: Mon Jan 28 18:23:32 2013 read : io=3594.7MB, bw=122645KB/s, iops=15330 , runt= 30008msec slat (usec): min=2 , max=2263 , avg= 5.92, stdev= 4.05 clat (usec): min=128 , max=51478 , avg=628.97, stdev=789.58 lat (usec): min=134 , max=51482 , avg=634.89, stdev=789.56 clat percentiles (usec): | 1.00th=[ 169], 5.00th=[ 185], 10.00th=[ 195], 20.00th=[ 213], | 30.00th=[ 237], 40.00th=[ 306], 50.00th=[ 572], 60.00th=[ 756], | 70.00th=[ 796], 80.00th=[ 868], 90.00th=[ 988], 95.00th=[ 1224], | 99.00th=[ 2640], 99.50th=[ 4832], 99.90th=[13376], 99.95th=[15040], | 99.99th=[15936] bw (KB/s) : min=17280, max=48528, per=33.37%, avg=40921.04, stdev=6090.31 write: io=918768KB, bw=30617KB/s, iops=3827 , runt= 30008msec slat (usec): min=3 , max=2260 , avg= 7.34, stdev= 6.94 clat (usec): min=262 , max=19853 , avg=577.21, stdev=629.07 lat (usec): min=271 , max=19862 , avg=584.54, stdev=629.35 clat percentiles (usec): | 1.00th=[ 338], 5.00th=[ 378], 10.00th=[ 402], 20.00th=[ 434], | 30.00th=[ 458], 40.00th=[ 482], 50.00th=[ 502], 60.00th=[ 532], | 70.00th=[ 564], 80.00th=[ 620], 90.00th=[ 732], 95.00th=[ 812], | 99.00th=[ 1304], 99.50th=[ 2768], 99.90th=[12224], 99.95th=[15168], | 99.99th=[15680] bw (KB/s) : min= 4080, max=12368, per=33.36%, avg=10213.68, stdev=1566.17 lat (usec) : 250=26.81%, 500=21.78%, 750=16.54%, 1000=26.96% lat (msec) : 2=6.67%, 4=0.69%, 10=0.37%, 20=0.18%, 50=0.01% lat (msec) : 100=0.01% cpu : usr=3.33%, sys=16.67%, ctx=0, majf=0, minf=0 IO depths : 1=0.1%, 2=0.1%, 4=100.0%, 8=0.0%, 16=0.0%, 32=0.0%, >=64=0.0% submit : 0=0.0%, 4=100.0%, 8=0.0%, 16=0.0%, 32=0.0%, 64=0.0%, >=64=0.0% complete : 0=0.0%, 4=100.0%, 8=0.0%, 16=0.0%, 32=0.0%, 64=0.0%, >=64=0.0% issued : total=r=460040/w=114846/d=0, short=r=0/w=0/d=0 Run status group 0 (all jobs): READ: io=3594.7MB, aggrb=122644KB/s, minb=122644KB/s, maxb=122644KB/s, mint=3 0008msec, maxt=30008msec WRITE: io=918768KB, aggrb=30617KB/s, minb=30617KB/s, maxb=30617KB/s, mint=3000 8msec, maxt=30008msec -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
