One of the reasons I bought a new laptop last year was because LR3 had become very slow ... almost unusably so in fact ... now having used LR4 for a few days, on a 2.7GHz i7 processor with 6GB of RAM, I'm finding nearly as slow as the old system ... the LR4 beta wasn't anywhere near as bad as this ... I'm wondering with tongue only partly in cheek whether this is why they reduced the UK price ... very very disappointing
EDIT:
With the release of LR 4.1, some of these problems have been significantly ameliorated - see post #73 here - https://www.photographerslounge.org...-very-disappointed-7321/index8.html#post82232
