Bitcoinqt is processing all RPC calls very slowly. My guess is due to many transactions. Idea to speed it up is following; move all coins from the wallet to another address which would merge all current transactions into one big input for next transactions.

I want to keep bitcoinqt accounting intact (all account balances there must be intact), so the idea is to do following:
1. create new receiving address with account name: "blabla"
2. send all bitcoins to that receiving address (payment to self)
3. issue rpc command: move blabla "" [btcamount]

I need input from bitcoin experts whether this would have any impact on speed of rpc calls. Rpc calls that are used are: sendfrom, move and getbalance.

Thank you for your help.
