Description
Build 6.0.0-1693
Observed that one node swap rebalance time is ~50-60% higher than one node rebalance in/out time.
First one node swap rebalance(3 -> 3) time: 230 min
Second one node swap rebalance(3 -> 3) time: 295 min
One node rebalance in(3 -> 4) time: 173 min
One node rebalance out(4 -> 3) time: 176 min

Could you give a bit more background on this issue? You've marked it as a bug, but this just sounds like an observation that swap rebalance takes longer than a single rebalance in?
As such, that doesn't sound like a bug to me (possibly an improvement?) - unless it's a regress from some previous build.
(As an aside, swap-rebalance is still quicker than node_in + node_out, so not clear this is even unexpected behaviour).
If you think this is a bug, please update to include expected behaviour and actual behaviour. If not then change to an improvement making clear what you think should be improved.
