You need more RAM, not more swap. 512MB is not enough. That's why the last few releases have been running progressively slower: They're running out of RAM and hitting the swap. If you can upgrade to 1 or, better, 2 or more GB RAM, your system will run much faster and won't need the swap as much.
My system (Athlon64 X2 2.7GB, 512MB swap--that's right MB!, F12-64-bit) has 4GB RAM and rarely uses the swap.
