The length maybe related to device writeback bandwidth.
Under normal bandwidth, each pause may last around 4ms and several times as shown in the trace above.
In extreme cases, fuse with unstable network backends,
if pauses occur frequently and bandwidth is low, each pause can exceed 10ms, the total duration of pauses can accumulate to second.
