DESCRIPTION
Note: Use of this command is not supported except with the direct assistance of Rational Customer Support.
The mvfstime command executes a command and reports on these statistics:
- Timing statistics,
- MVFS usage statistics; for information about these, see the Administrator's Guide,.
Use this command to perform timing experiments for applications running in a ClearCase environment.
The statistics gathered while command is running under mvfstime are systemwide statistics for that time period and are not limited to that command's activities. To get an accurate reading of the MVFS activity of command, make sure that no other activity is taking place on the machine when you invoke mvfstime.
For information about UNIX statistics, see the csh(1) reference page.
EXAMPLES
- Generate
timing statistics for an invocation of the clearmake program.
