Is the system otherwise responsive during the zfs sync cycles?
I ask because I think I'm seeing a similar thing - except that it's not only
other writers that block , it seems like other interrupts are blocked.
Pinging my zfs server in 1s intervals results in large delays while the
system syncs, followed by normal response times while the system buffers more
input...
I don't see any such problems unless compression is enabled. When
compression is enabled, the TXG sync causes definite response time
issues in the system.
