Bitcoin-qt 25% CPU and 500MB RAM

[lontivero]

Hi,

I wanted to consolidate all my wallets in one, just to have only one balance (because I has some satoshis here and there) so, I did a wallet backup 328 KBs and restore a 2 year-old wallet that I had with several small transactions and also imported the wallets that I had in my other computers. Finally I imported the backuped wallet's private keys. After that (almost 40 minutes), I had a 8MBs wallet and the bitcoin-qt client started to use 25% CPU and almost 500MBs RAM.

After this I restored the 328KBs wallet (it has just a couple of addresses and transactions) and all go back to normal. Is this the expected consumption?

if you open the debug.log ... you can see that bitcoin core must read all the block since the creation of your wallet.
not a problem.

when i have restored my january 2014 wallet, i must wait like 2 minutes.

all android wallet does the same think (with merkle tree summary).

decrease cache to 4Mb in bitcoin core help a lot in poor system (2go of RAM) ... but request more reading on disc in node mode.

I know that. The problem is that it was consuming that cpu and memory forever, even after calculate the final balance.
