Very slow multicam -- can I make it better?

Hi-

I'm trying to do a multicam edit using PP CC 7.1 on a late 2010/early 2011 Macbook pro (2.2 GHz i7/8 GB RAM, Radeon HD 6750,1024 MB). The sequence is using two clips from a couple of EX3s (30p) and HDV from a Canon XHA1 (also at 30p). The playback is so slow/choppy-- I think I'm getting something like one frame every three seconds. I haven't timed it, it just feels that way. Anyhow, it's almost impossible to edit this way. I have playback resolution set to 1/4. Is there something I can do to make this perform better? Render, transcode, setting somewhere? Or is it just too much to ask from this machine?

Thanks.

I forgot to add... OSX 10.7.4. And it's an early 2011 machine, not late 2010.

Where is your media? On one internal HDD? Or on external HDDs?

It's on external drives, connected via eSATA card.

So I tried again last night.... and the performance was great! So, glad it's working well now-- very well-- but I wish I knew WHY it didn't work well before so I could get around it in the future.

Was it creating the cache files for the source files while you were attempting to cut it? That will slow it down without a doubt.

That would also explain why it's suddenly snappy...

I'd recommend getting some RAM though...I use 16 GB in my laptop and I don't think I'd recommend less.
