Looks a little bit different but still a great method for speed improovement on armbian bullseye. Thank you!

It was already on performance 🙁
I just noticed that 104 is now the latest kernel, so I ran your script and now its even worse haha.

Have a look at my post: http://forum.odroid.com/viewtopic.php?f=98&t=14907&p=172156#p172994 Maybe this helps. But I bet you’ll get more if you set your cpu governor to performance.

great update, i was hitting 870 and after the update hitting 940!
ive been having massive issues with my Probox getting dropped from the XU4 (EXT4 – copying files/streaming/etc and it just randomly disconnects) so I upgraded the kernel (3.10.96 -> 3.10.103) having had one drop, but now,

(not sure which ones up/down) one way only maxes out at around 630-640)

any ideas?
