WAlking speed too slow - is there a console command...

...to speed up the basic walking pace? I'm not talking mad fast; maybe just a 10-20% boost, cos it seems to me that movement is a little sluggish. It's not a graphics thing as everything runs a-OK but navigating some of the bigger levels (5, for example) feels a little bit laboured, especially when you're hunting for secret areas down long passageways etc etc.
