I need some good fast paced jigs and reels. Any suggestions?
Sure.
Get Mary Bergins music off emusic.com, a tweaked E flat whistle and start playing along.
You will learn a lot.
He said fast, not break-neck! 
Joanie Madden - Hyness March/Johnny Harlings/The Lasses Of Ballintra
Mary Bergin - Richard Dwyers
Red Haired Boy and Geese in the Bog are nice and quick.
Never seizes to amaze me that I can even play them.
And you can get Julia Delaney moving as well. You’ll need a C whistle though.
Hope this helps.

Where to start. You want sheet music or CDs?
Sheet.
Well Palmer’s Gate is a great reel. The Roaring Barmaid is one of my favorite Jigs.
Try playing cut number 5 on Lunasa’s Kinnity Sessions CD. There’s some speed in that one.
Errr… you do realize they go as fast as you play them, yes? While there are certainly some jigs and reels that sound nice slow, in general, they can all be played at a good clip.
Sean sa Ceo (John In The Fog) is a great 3 part reel that I like to use to check out new whistles. Sounds great as fast as you can play it, anthough it’s pretty good slower too.
Yeah, my response was going to be “all of them”. Can you narrow the
field any? Is there a particular application you’re interested in? Any
key? Single jigs, double jigs, slip jigs?
For reels, I’m partial to Cooley’s, Sheehan’s, Cup of Tea, Dick Gossip’s
For jigs, I like Morrison’s, Swallowtail, Atholl Highlanders, Kid on a Mountain
Most of these can be found here
Interestingly enough, that version of Dick Gossip’s on that site has the A and B parts switched from the way I learned it. 
Try Gravel Walk. . .always a nice one for blazing speed.
killer tune- wolvy and I had a long discussion about it in one of the other fora. It’s tricky until the octave jumps get comfortable though.
One that works really well fast but is fairly easy is the 2nd tune called “Robbie Hannan’s Jig” from Jerry O’Sullivan’s album The Invasion
Dick Gossip’s (AKA The Castle) is one of those tunes where there is some disagreement over which part is first. Personally, I like to start it with the low part if I’m starting a set with it, and start it on the high part if I’m going into it from another tune in a noisy pub.
Michael Coleman does Jackson’s (Humours of Kesh) quite fast and it is quite melodic. I play it with Wheels of the World at a very quick pace.
