Dear all,

i have been using Armbian bionic currently running kernel 4.4.156-rockchip64, for sharing files over the internet, i am currently using sshfs. Openssl benchmark ls as followed

However, when it comes to sshfs speeds, i can only reach around 20-25MBytes per second

> fallocate -l 1G /tmp/largefile
> pv /tmp/largefile > /srv/tmp/test_largefile
1.00GiB 0:00:46 [22.0MiB/s] [==============================================================================================================================================>] 100%

Do i need AF_ALG to actually speedup sshfs speed? or is this board not fast enough to achieve higher sshfs speeds?
Note : the cpu loading is not that high on sshfs copying
Thanks a lot for your help

over scp, i average around 30-35MBs:

root@chromebox:/home/jmandawg# scp random500MBfile renegade:/mnt/data/
root@renegade's password:
