.Sh DESCRIPTION
.Nm
is a command line tool to measure the time spent to serve withdrawals/deposits/refreshes.
It usually needs a dedicate configuration file where all the services - the exchange and the (fake)bank - listen to URLs not subject to any reverse proxy, as say Nginx.
Moreover, the benchmark runs on a "volatile" database, that means that table are always erased during a single benchmark run.

.It Fl c Ar CONFIG_FILENAME | Fl \-config= Ns Ar CONFIG_FILENAME
(Mandatory) Use CONFIG_FILENAME.
.It Fl b Ar BANK_URL | Fl --bank-url= Ns Ar BANK_URL
(Mandatory) The URL where the fakebank listens at.
Must match the host component in the exchange's escrow account "payto" URL.
.It Fl n Ar HOWMANY_COINS | Fl \-coins-number= Ns Ar 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 REFRESH_PROBABILITY probability, which is (hardcoded as) 0.1; future versions of this tool should offer this parameter as a CLI option.
.It Fl l Ar LOGLEVEL | Fl \-log\-level= Ns Ar LOGLEVEL
GNUnet-compatible log level, takes values "ERROR/WARNING/INFO/DEBUG"
.It Fl h | \-help
Prints a compiled-in help text.
