Hi, i'm experiencing strange thing. After updating my wallet to RC5 it's start to load new bloks from blockchain very sow (about 1 per sec). I deleted all but wallet.dat and start from 0 to update blockchain. It's started loading fast but continuosly slowing loading speed to the same (1 block/sec). I'm waiting 2h and still "5 weeks behind". Any ideas why this is happening? And how to solve?
