iperf on direct connection got 900mbps (1ms)
with lcvpn 500mbps

iperf over internet 600mbps stables between 2 servers(50ms)
with lcvpn 30mbps

Why this diference?

@segator do you have zero packet loss? tested now between Prague and Berlin and have about 200mbps - same result as with 2 servers in one datacenter... other idea is about MTU - is there some router with lower MTU than 1500? if yes there will be fragmentation and defragmentation which can affect speed

No packet loss, direct iperf have good speed, tried with diferents mtu, same results

@segator hard to say :-( what about cpu load and memory usage? I really can't see any possible problem as lcvpn use UDP transport, so no confirmation needed on packet receive an so on - each packet is individual and just "encrypted/decrypted and forwarded to other interface"

Cpu usage its not on the max usage, 30-50%
