(Quote) The read and write tests are being done concurrently, not independently. Both are added together to get the full IOPS load the disk was under during the test. Also, this test isn't really designed to show the absolutely maximum performance,…

Looks like zfs' built-in readlimit & sendlimit options are what you're looking for. I don't use zfs myself, but here's the commands: zfs set writelimit=10mb rpool/my/poolzfs set readlimit=10mb rpool/my/pool Just set it to something low so that…

(Quote) Sounds like a good idea to me! Would make some interesting graphs if you plot the read, write, and cumulative speed results independent of each other on the same graph.

(Quote) Could be the case! It probably all boils down to what is actually being represented in the test. Are we copying a large video file or making many database updates to many distinct tables, rows? I'd imagine the fio parameters would vary widel…

That's a negative for me, sir. Have more compute power than I have anything to do with at the moment. Thanks for the offer!

(Quote) If given the option, I'd opt for 512k. If you look through the YABS results thread, nearly every single test does better (in bandwidth terms) with bs=512k over bs=4k. The low block sizes are really just to stress test how many IOPS you can …

(Quote) Good write up, Ant! Just a quick thought I had -- for your extended fio tests, you're limiting the block size to just 64k, when in reality the block size will likely be higher as the system tries to use what is most optimal. The yabs test s…

(Quote) Boot to rescue, dd /dev/sdb to /dev/sda, reboot with fingers crossed. That's my guess at least, but wait for a second opinion.

(Quote) Cheers! I still think about this damn song every time I see "Guacamole" lol... https://youtu.be/JNsKvZo6MDs Have a splendid day!

(Quote) Thanks for the ping, I'm surprised you remembered that I use this! My couple RDP boxes are on my local net, so I suppose I have other things to worry about if any of those systems become compromised :P. Time to patch!

Hey all, I just pushed some minor updates to the YABS repo. Summary of changes below. Please give me a shout if anyone hits any issues with the script! We had 234 script runs yesterday (first time it's been over 200), which I thought was pretty cool…
