The execution time is in micro-second and the threshold is set to 1000
us only. Maybe it is not suitable for the situation.
BTW, why zk_event_handler is involved in trace module? Does anyone know
about it?

Hi, All
I create a 10 nodes' sheepdog cluster with zookeeper driver. My NIC and switch
are all 10G, but the sheepdog log always warns "wastes too much time in event
loop".
Is it critical and what causes it?
Please see the logs as follows:
