The suits are designed to be a smooth as shark skin, and it takes 30 minutes for a swimmer to get into it. Also, I heard that suits actually help with buoyancy of the swimmer, keeping them higher up in the water.
And you can design a "fast" pool.
The pool in Beijing has 10 lanes, but only use 8. This keeps the wake caused by the swimmers in the outsides to to dissipate more before rebounding back into the swimming lane.
The pool is also deeper than most other pools. This has the same effect. The ripples that move downwards towards the bottom of the pool, and bounce back up towards the swimmers again dissipates more, causing less disturbance that the swimmer has to swim through.
