My SSD died - I took another one, cloned again from the spinning disk - works *douh* - without any throttling! If I run again in this situation, the real hardware might be the culprit. Sorry for the time this issue took. But I will try to make some deeper investigation on this issue - because it worked with 1.2.0 and 1.6.50 failed... Best regards, Erik
