Could it be because of 2 much idling ? When i lookk at the miners log , see lots of "set work ttys 1 ttys 2 and 3 -4 "

Not lots of accepted work or new jobs . My reject rate never goes over 6-8% . Noticed even when i reboot the miner and my reject rate is below 3% , hashrate is still between 480-510

Maybe but I don't see much of any improvement until a firmware update that has been promised soon. A couple of things I DO like about the L21: They are very cool. It's almost impossible to overheat them if they get fresh air. The other thing I like about them is that they provide us with a lot of flexibility in our power circuit planning. We can get three L21s and 2 L3+ miners on a 20 amp, 220V circuit with a full 80% utilization. Makes planning flexible. Hopefully, the firmware update will smooth out any performance issues.
