When I look at my mining rig I get about 6 Gh/s on one of my rigs. When I check the hashrate on the pool's web site it shows about 1/2 of what the hasrate shows on the mining pool site. Why is this? Do I need to adjust some settings so both match? If I need to change a setting in CGMiner which setting would I change?
Hard to say what you need to change without any details of your setup. However, you will see that your hashrate at the pool will fluctuate. Sometimes it will be high, sometimes it will be low. It's fairly normal.
