Private Key Importing

[sudocoin]

Hello, I have running bitcoind on Ubuntu 12.04 LTS with dual core AMD 3.6 GHz. When I import a private key its takes roughly 8-10 minutes for it to finish. What is limiting this speed, CPU? If I were to purchases a top of the line Intel i7 say, could I reduce that time it takes to import? Any other suggestions to increase this speed?

Also, how many private keys can a bitcoin server wallet safely handle before possibly becoming unstable?

I am using a bulk wallet generator to pre-generate lots of public/private key pairs. I import the corresponding private keys when the funds are needed. Eventually there could be thousands of imported private keys.

Thanks for all the help.

Some users report slowness when bitcoind is holding 200000+ keys. The fastest way to import is to use pywallet.

Thanks for the reply. Before I change my importing scheme, do you have a rough estimate of the import speed increase using pywallet. If it takes 8-10 minutes using bitcoind, do you have a rough estimate of how long it will take for pywallet... 5 minutes? Also, if I stay using bitcoind, can I upgrade my hardware to increase speed? Thanks again!

I remember a topic there was a topic that discusses the time of pywallet vs json-rpc commands, and pywallet was considerably faster but I don't have the link. The limiting factor when importing is probably the hard drive because of the wallet database transactions (assuming you're not rescanning after every key imported).
