NFS is very slow through soekris vpn and eop device.
Looking at the dump, this is mostly a latency problem:
6-8ms round-trip on getattr (from ls)
(time between calls is 1/100 of that)
Corresponds to ping times. Ping also sees larger delays.
( I'm typing this on a TCP connection and can clearly see there are
dropouts as well. )
Ping time without VPN is 4.5ms and seemingly more stable.
Ping on LAN is 0.2-0.6, more than an order of magnitude less latency.
Ping on Wifi is very variable. 6-20 ms.
But over VPN it is again smaller? Nope just variable 4 ms wifi, 6ms wifi+vpn.
Troughput is horrible. Chokes after 1GB.
Mabye because of async?
HA! I know what the problem is. My prompt is accessing the current
git directory to display the branch name. That is causing a lot of access.
Too many interactions!
