I think, before any optimizations, you need to find the exact cause of the lags. Is it rendering or AI pathfinding/logic. I found this thread, wich can be helpful:

It hasn’t improved really that much, I have done some extend testing on it in recent versions. 400 AI’s Without AI: 11MS Without Movement: 14.5MS PawnMovement: 18MS (acceptable performance, but the quality is not suitable) CharacterMovement: 28MS (Bad performance…) CharacterNavmeshwalking: 27MS (literally just as bad) In conclusion I’m still looking for a suitable AI\_Movement Solution. I hoped the MOBA AI Twitch stream would give some…

To find the exact reason i recommend you to start from simplest solution. Like actor, without navigation, Just “dumb” setactortransform in direction towards player every tick.  
Try use performance profiling tools to identificate the problem.
