The battle speed is rather fast in my opinion. It appears to me to be faster than RTW but I may be wrong in that. however, there is a mod available at the TWC site that reduces combat speed and provides several variations. This is nice as you choose to keep cav speed slightly faster than infantry. Also it is stand alone so you don't have to use Darth or other more extensive mods if you don't wish to.
