Hi, i have two miners right now, one running on a 6870, and another one running on a 6850... each miner is using 25% of cpu, witch gives me a steady 50% cpu usage.
using guiminer with podlbm... both of podlbm process are using 25% cpu. This is normal?
You have a 4-core CPU, and each one is taking a full core.
The reason for that is that the loops running in poclbm that check for new results or long polling triggers have absolutely no delay between iterations, so it runs as fast as possible, taking 100% of the core. The only reason it doesn't take more is because it isn't written to use multiple cores.
Were it to sleep 1 second per iteration, it would drop to < 1% total CPU usage on a higher end quad core.
It's been a problem with poclbm for quite some time.
