I'm running bitcoind and generate a bunch of bitcoin addresses. I use a PHP script and an Apache2 server to make calls to the RPC API.
bitcoind uses ~ 0.7%-2.2% of the CPU and writes ~3 MB/s on the SSD. Apache2 uses ~0.3% of the CPU.
I set -rpcthreads to 8 but that didn't do anything for me.
Where is the bottleneck? Is there a way to speed the hole process up?
I know that vanitygen can create a lot of addresses but then I would need another step to add them all to a wallet therefor I would prefer using bitcoind. bitcoin-qt is just awful slow at the same task with RPC commands.
