-l FILENAME | –logfile=FILENAME

Send logging output to FILENAME.

-n HOWMANY_COINS | –coins-number=HOWMANY_COINS

Defaults to 1. Specifies how many coins this benchmark should withdraw and spend. After being spent, each coin will be refreshed with a probability RATE (see option --refresh-rate).

-p NPROCS | –parallelism=NPROCS

Run with NPROCS client processes.

-R RATE | –refresh-rate=RATE

Defaults to 10. Probability of refresh per coin (0-100).
