Upgrade worked. Thanks.

i wasn´t talking about the autotuning at this time. i was talking about the displayed hashrate. But i found out, why this is as it is.
cgminer calcualtes the hasrate directly based on the number of processed calculations.
cpuminer makes the calculation based on the accepted shares and so it takes longer until enough accepted shares are there, to make a precise calculation. so at the beginning cpuminer shows a lower hashrate, then it´s realy doing. thats ok for me.

so now let´s talk about autotuning. i already have some ready tuned grids, but somtimes i add a new device. i tried this today with a combination of fixed frequencies and autotuning on, but cpuminer always crashes after a minute. now i have to start the whole autotuning process again for all devices, if i add a single device.
it would be nice to get a button button on the dashboard for every device, like "lock frequency". then i´m able to lock the already autotuned devices and only the new devices should be autotuned. i think this requires work on the minera and the cpuminer source but it would be very usefull for people who change there grids or add new ones from time to time.

Another cool feature would be a rescan devices button. if i add a device, i have to restart cpuminer. else the new device will not be detected. cgminer detects new device when they are pluged to the maschine and adds them without restart.
