FCP 10.1 slow timeline and editing - Any suggestions to improve speed?

Recently updated to OS X 10.9.1 and FCP 10.1. Now experiencing very slow editing and movement in timeline. FCP is responding some 2 to 5 seconds after providing an editing command. The slowest response is to scrolling in the timeline - 2 finger scroll does not respond for up to 10 seconds after doing it.

Render times are fine and similar to previous FCP X versions.

Never had this problem in previous versions of FCP X.

So far I have done the following things based on forums and a call to apple support(?).

Deleted all plug ins.

Started from scratch a project that I was half way through and imported all clips from scratch to a new Library (external Hard Drive).

Deleted FCP and reinstalled including deleting all preferences.

Timeline is quick in the early stages of the project but gets slower as I progress - about 3 minutes into my project now (approx 200 clips) and editing time is becoming impossible.

Am using Mac Book Pro with 2.5 GhzIntel Core i7, 8GB 1333 MHz DDR3, Intel HD Graphics 3000 512 MB.

Anyone able to assist with further suggestions?

Thanks

Final Cut Pro X, OS X Mountain Lion

Is your hard drive more than 80% full?

Are you using an external hard drive (as you should)?

What is the format of your source media and is it exactly the same as that used in earlier "successful" FCP X projects?

Also…open Activity Monitor and check on the Mac's memory during the slow-dowm process.

Are any of your 200 clips large photos?

Hi Ian and Russ

THanks for your interest.

Hard drive is 500GB of which I have used approx 300. I am using an external hard drive for this project.. Footage is from Canon 7D/70D which is H.264 which is the same as other successful projects.

Yes I do have a number of photos (18mp) that I am using as part of the project although I have used these before without impact.

I will open activity monitor and report.

Tried activity monitor (first time I had used it).

When scrowling through time line (one of the problem activities) memory does not move much- Real memory approx 925mb, Virtual memory 6GB, shared memory 44mb, Private memory 75mb. Interstingly though when performing this task CPU usage goes > 100% and averages 130%.
