.SH DESCRIPTION
.sp
\fBtaler\-exchange\-benchmark\fP is a command\-line tool to measure the time
spent to serve withdrawals/deposits/refreshes.  Before running the benchmark,
the GNU Taler services must already be running at the configured addresses.

\fB\-c\fP \fICONFIG_FILENAME\fP | \fB\-\-config=\fP‌\fICONFIG_FILENAME\fP
(Mandatory) Use CONFIG_FILENAME.
.TP
\fB\-F\fP | \fB\-\-reserves\-first\fP
Create all reserves first, before starting normal operations.
.TP
\fB\-f\fP | \fB\-\-fakebank\fP
Expect to interact with a fakebank instead of libeufin.
.TP
\fB\-h\fP | \fB\-\-help\fP
Prints a compiled\-in help text.
.TP
\fB\-L\fP \fILOGLEVEL\fP | \fB\-\-log\-level=\fP‌\fILOGLEVEL\fP

.TP
\fB\-p\fP \fINPROCS\fP | \fB\-\-parallelism=\fP\fINPROCS\fP
Run with \fINPROCS\fP client processes.
.TP
\fB\-R\fP \fIRATE\fP | \fB\-\-refresh\-rate=\fP\fIRATE\fP
Defaults to 10.  Probability of refresh per coin (0\-100).
.TP
\fB\-r\fP \fIN\fP | \fB\-\-reserves=\fP\fIN\fP
Create \fIN\fP reserves per client.
.TP
\fB\-u\fP \fISECTION\fP | \fB\-\-exchange\-account\-section=\fP\fISECTION\fP
