Help with Speed

Hey everyone, I was just wondering if some of the more experienced members here (aka nearly everyone here haha) how do you train for hand speed? I practice Eskrima so this is very important to me. I already try to put in at least 30-60 minutes of going throw the different "counts" i've learned (4 count, 6 count, 8 count, the variations i.e. "broken" and so forth). I think this will increase speed in the long term, but is there a more effective way to do this?

Thanks! And I'm not just asking eskrimadors, I'm asking anyone who trains for hand speed; i.e. boxers, Chunners, etc. I'll probably move this to a more general forum, but since I'm asking specifically for Eskrima, I thought I'd post here first.

Again, thank you~
