tcbmttest \- test cases of the B+ tree database API

.SH DESCRIPTION
.PP
The command `\fBtcbmttest\fR' is a utility for facility test and performance test.  This command is used in the following format.  `\fIpath\fR' specifies the path of a database file.  `\fItnum\fR' specifies the number of running threads.  `\fIrnum\fR' specifies the number of iterations.  `\fIlmemb\fR' specifies the number of members in each leaf page.  `\fInmemb\fR' specifies the number of members in each non\-leaf page.  `\fIbnum\fR' specifies the number of buckets.  `\fIapow\fR' specifies the power of the alignment.  `\fIfpow\fR' specifies the power of the free block pool.
