The command `kchashtest' is a utility for facility test and performance test of the file hash database.
This command is used in the following format. `path' specifies the path of a database file. `rnum'
specifies the number of iterations.

Performs test of transaction.
Options feature the following.
-thnum : specifies the number of worker threads.
-rnd : performs random test.
-set : performs setting operation only.
-get : performs getting operation only.
-getw : performs getting with a buffer operation only.
-rem : performs removing operation only.
-etc : performs miscellaneous operations.
-tran : performs transaction.
-oat : opens the database with the auto transaction option.
-oas : opens the database with the auto synchronization option.
-onl : opens the database with the no locking option.
-otl : opens the database with the try locking option.
-onr : opens the database with the no auto repair option.
-apownum : specifies the power of the alignment of record size.
-fpownum : specifies the power of the capacity of the free block pool.
-ts : tunes the database with the small option.
-tl : tunes the database with the linear option.
-tc : tunes the database with the compression option.
-bnumnum : specifies the number of buckets of the hash table.
-msiznum : specifies the size of the memory-mapped region.
-dfunitnum : specifies the unit step number of auto defragmentation.
-lv : reports all errors.
-itnum : specifies the number of repetition.
-hard : performs physical synchronization.
This command returns 0 on success, another on failure.
