Logging using "write_bw_log" seems off

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi

I was trying to draw some performance graphs executing a sequence like

1 Sequential write
3 Random writes
25% trim command
3 Sequential writes

I observed a discrepancy in the bandwidth logging for last two
sequential writes.
I notice that the last two sequential writes differ by 300 MB/s but
the last individual reading of these logs indicate that the slower
sequential write actually took slightly less time to complete.
Capacity is 4TB.

Can you provide some inputs if this is a known issue?
I am using fio-2.2.10.

Thanks,
Shivam
