Weird performance improvement (and loss again)

A washing machine? ;)

Edit:
Its just a weird net transfer graph, no idea whats causing it, just saw it.
I will run tests before expecting senseful answers , just looks weird and funny ;)
Happened today after i switched sata power supply lines (and a jumper on the backplane away from i2c ), will have to check that tomorrow

Ah whatever caused that - new day, now gone. Lets wait when it's going to be back;)
