I've been running fio on an iSCSI volume where I can monitor things like the network traffic (to ensure that indeed it is flowing) as well as on the machine the volume is hosted on. I'm seeing a steady state of 300MB/s, but when I stop the FIO process and writes the detailed bandwidth and iops logs, there's segments where iops drop to 0, but bandwidth for the same time point is somewhere around the single digits or teens. Has anyone else seen this behavior? Does anyone have an idea why I might be seeing this? Here is the job file I ran: [global] ioengine=windowsaio do_verify=0 offset=0 write_bw_log=C:\\haggis\\manualfio\\stats-running write_iops_log=C:\\haggis\\manualfio\\stats-running write_lat_log=C:\\haggis\\manualfio\\stats-running verify=crc32c-intel runtime=292000 thread [fio-0] filename=\\.\PhysicalDrive1 iodepth=1 blocksize=256k readwrite=write [fio-1] filename=\\.\PhysicalDrive2 iodepth=1 blocksize=256k readwrite=write -- 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
