http://dev.bukkit.org/bukkit-plugins/nocheatplus/tickets/644-optimization-help/NoCheat can not really be the reference anymore, Minecraft cheats have changed by a good bit. But of course you can disable some things in order to gain some performance, though it is not certain which ones really gain you that much worth the time configuring. Note that NCP is running on 500 slot servers with mostly the default configuration, except for logging turned off usually.
Do you happen to have profiler output or timings for this on your server? Can you show your NCP configuration as well?
Guessing without knowing what your configuration looks like, quite efficient might be:
Reduce logging by a lot:
Disable all logging.
Alternative: Reduce file logging, disable completely or keep only one of console / file.
Alternative: Only log extreme violations or those for which you want mods to teleport to a player.
Reduce SurvivalFly accuracy
Disable vertical accounting: allows gliding and similar.
Disable the hover check or increase the ticks (period): Allows hovering in-air.
Reduce Passable accuracy
Reduce ray-tracing use:
Set vcliponly to true: Allow horizontal moving through blocks. Very thick walls can not be passed through
Keep blockchangeonly at true: only perform ray-tracing if the player is moving across blocks.
Alternative: Disable ray tracing completely: allows moving through walls but not into, specifically opens vclip down.
Reduce Combined checking (uncertain if this really gains enough):
Disable improbable: more "classic": allows fast fighting over a long time.
Disable yawrate: not recommended: removes penalties for very fast turning around for fighting and other.
Block breaking (really uncertain if the tiny performance gain is worth disabling):
If you want to allow "moderate nuking", you can disable fastbreak.
Further you can disable some random checks which you don't think you need, but do ensure you are ok with players doing what the check is said to prevent. Do not disable morepackets checks, but inventory.fastclick and inventory.items are checks that you might not need (allow inventory tweaks).
