You should ignore the time it takes the first time, because that is used to read pieces of program and data into memory, which varies a lot, in addition to the time it takes to run the program. The second time, it is already in memory, so the time is largely the time to run the program. That's why it is a lot faster and also more consistent, which makes it a more reliable way to do comparisons relative to other solutions..

runlim
RUNLIM(1) General Commands Manual RUNLIM(1)
NAME
runlim - a program to run benchmarks
SYNOPSIS
runlim [ options ...] command [ arguments ...]
DESCRIPTION
run is a tool that can be used to run and control benchmarks. It executes a given command with (optional) arguments, samples resource
usage during the run, and kills the process (and its child processes) if a certain time and/or space limit is exhausted.
Every 100 milliseconds, runlim takes a sample of the program's resource utilization, and logs status information to stderr every second.
Optionally, the status can be logged to a file.
Multi-threaded programs can be limited by setting a wall clock timeout. runlim follows the time accumulation scheme of GNU time for multi-
threaded programs and programs that spawn multiple child-processes: time spent in each thread/child is summed up, unless you are only
interested in walk clock time.
OPTIONS
runlim accepts the following options:
-h, --help
Show summary of options.
--version
Show version of program.
-o FILE, --output-file=FILE
Overwrite or create FILE for output logging.
-s NUM, --space-limit=NUM
Set space limit to NUM megabytes.
-t NUM, --time-limit=NUM
Set time limit to NUM seconds.
-r NUM, --real-time-limit=NUM
Set real time limit to NUM seconds.
-k, --kill
Propagate signals.
SEE ALSO
time(1), timelimit(1), timeout(1), time(7).
