Get rid of Buffspells!
Or get rid of dispel magic as a debuff; IME, the major hassle comes when folks have to refigure numbers in combat, so either buffs in combat, or debuffs (especially area ones) slow things down.
I don't find grapples especially slow things down; I think we've got grapples down (at least the way we do 'em, which I think is mostly by RAW). The only real impact they have is that they can be dangerous for PCs, but that usually tends to focus the players' attention, and often leads to the grappler dying rapidly.
Of course, the players don't initiate grapples very often, and the now-20th level PCs I'm GMing for are anti-grapple machines. Lots of bolt shirts; a sorcerer with dimension door, tactical teleport, and benign transposition; two or three people with rings of freedom of movement; a fighter with the +10 to resist grapple augment crystal, Combat Reflexes, and Close Quarters Fighting (he got an 80-odd grapple check Saturday to resist being hugged by an advanced half-dragon dire bear); and the archer has Improved Precise Shot, so he can safely fire into grapples. So, nowadays, nobody stays grappled for long!
Another trick I sometimes use, stolen from Ben Robbins: the hit point pile.
