Problems with MTU in logs like “Bad encapsulated packet length from peer (20559), which must be > 0 and <= 1626” might be mitigated sometimes by adding this commands in “Advanced” field on the Server configuration page:

For TCP server use mssfix;
Tor UDP server use fragment XXXX; where XXXX is desired MTU value

 

Fix bad speed with help of MTU tuning:
