How to read juicefs profile <mount-point>/.accesslog

[myc724]

Is there any document explaining the meaning of these columns? Thanks! It seems columns #3 and #4 are the averages and total times to execute each operation. How about column #5 (where some are over 100%)? The profiling doc does not have a column ?#5.

The "Percent(%)" column equals Total(us) / Interval. For example in your "example output 2", the Total(us) of lookup operation is 2517482, the default value of Internal is 2 seconds (specify by --interval option), so 2517482 / 2000000 * 100 = 125.9.

For operation that percentage over 100%, it means there're multiple processes or multiple threads call this operation.
