Ruby Benchmark module: meanings of "user", "system", and "real"?
These are the same times that the Unix time command or other typical benchmarking tools would report:
- user: the amount of time spent executing userspace code (i.e.: your code),
- system: the amount of time spent executing kernel code and
- real: the "real" amount of time it took to execute the code (i.e. system + user + time spent waiting for I/O, network, disk, user input, etc.). Also known as "wallclock time".
Please check this gem:https://github.com/igorkasyanchuk/benchmark_methods
No more code like this:
t = Time.nowuser.calculate_reportputs Time.now - tNow you can do:
benchmark :calculate_report # in classAnd just call your method
user.calculate_report
