Newbie question: Just installed Bitcoin Core 2 days ago. Start synchronizing the block chain since (24 hours x 2) on Macbook 10.9.3  So far, I got only "Processed 239569 blocks, last received block generated 1 year and 16 weeks ago". The last received block still changing but...
     Why it is painfully slow like this? Any tip to accelerate the speed of synchronizing ?

Thanks a bunch for any advise.
