Client pegs my CPU

September 14, 2011, 11:48:23 PM

The official Bitcoin client always pegs my CPU to 100% when it's running. This makes everything run slowly. Other people don't seem to have this problem. Any ideas?

Running OSX 10.6.8, client version 0.3.24-beta

Every time a block is mined, a certain amount of BTC (called the subsidy) is created out of thin air and given to the miner. The subsidy halves every four years and will reach 0 in about 130 years.

You could change the config file so it doesn't automatically start generating coins every time you start...CPU mining is virtually pointless now anyway

I'm pretty sure I have that option turned off. Wasn't it removed from the client anyway?

It's removed from the settings dialog but you can still enable it in the config file or command line.

What block number does it report in the lower right? It's normal for it to use a lot of CPU and IO until it's finished downloading and verifying the block chain.

Yes, it's catching up on the block chain. If using 100% of the CPU is intentional, I guess it's just bad design.

Verifying history just takes a lot of CPU. The fix people are discussing is to download some pre-verified chunks to seed it to 98% and then just process the last 2%, but that's not ready yet.

Another fix would be to use at most, say, 50% of CPU. I'm sure most users would prefer that to the current operation, and it's a simpler change than downloading pre-verified chunks.

Is it possible to reduce Task/Process/Thread Priority in OSX ?
Every half decent OS has Ways to do that, so there is hope. Grin

By the way, whats your Hardware ? A faster CPU with more Cores might help a little...
