That was my wallet with over 8000 blocks, here is another follow up to reducing cpu use, the number of blocks and the size of the wallet.dat file itself.

That original wallet.dat file increased in size to over 13mb so I decided to move all of the coins to a new wallet.dat after they staked, this took some time (20 days to not lose coin age) and during the process I maintained 2 wallet.dat files and kept renaming them back and forth until I had all coins moved to the new wallet.dat. 

The original wallet.dat which is now empty with a balance of 0 coins is still 13.7 meg.  The new wallet which has all of my coins in 3 blocks is 300kb, and cpu use is 2-3%.  Added bonus is that the reduced size wastes less space on the SSD drive as well as on the usb thumb drives used as backups.  It's working great and the larger blocks stake instantly once they hit 20 days.

Now if Cryptsy would actually fix their wallet I could get some more coins staking, it's been in maintenance mode far too long.
