By the way, I have four Mac's in the house. Not even the Mac Pro which is just a few years old can process a RAW image in milliseconds. Depending on JPG size 4 to 7 seconds is the norm. Well over an hour for 1000 images. Maybe I should be asking what Mac you have if it can process a full size RAW file from a 5D in a few milliseconds.
Well, ms is an exaggeration - but it is not seconds either. I can preview 5DII CR2 files in the finder at full-size without significant delay (C2Duo 17" 2.8GHz with a dual HDD configuration using a 7200RPM mechanical disk plus SSD; 8GB RAM). It is difficult to gauge performance in Lightroom directly because of its caching behaviour, but I don't see a whole lot of difference between large hi-resolution JPEGs and the equivalent RAW files.
I used to have serious problems with Lightroom catalogue performance, but these disappeared with LR4 and moving both the LR catalogue and cache files to the SSD. Perceived performance in Lightroom seems often down to it generating large preview files or paging. Another problem that will affect performance with imports is RAM size - even with 8GB it is possible for LR to trigger paging due to lack of memory if other apps are open (esp PS).
I might try benchmarking the Apple RAW converter, as I have written some software that uses it to batch process RAW files in the past.
