Actually, LR does benefit from multiple CPU cores as it is a fully threaded application, but it takes some manual effort and changes in workflow to get the most from it. For instance, if you select 1000 raw files and tell LR to export them, it will operate mostly serially, making poor use of the multiple core system and it's threading. But if you instead select four batches of 250 images and tell LR to export each batch concurrently (say export on each batch without waiting for the previous one to complete), you'll see it use all the cores and get the job done in typically half the time, plus or minus. Same goes for other concurrent operations. I expect Adobe will automate this more as time goes on.
