anyone else had a problem with ipsec through ipip on RouterOS (i tried v4.17, v5.11 and v5.21) with high cpu usage?
1.5mbps was enough to get 100% cpu on RB433AH which cpu runs on 680MHz - I checked it just to be sure.
Strangely, on v6.0rc1 and v6.0rc2 works much better (20-30% on 3mbps).
CPU goes to 100% when data is coming through ipip interface, cisco is on the other side of the tunnel.
