You should use the listOSM and listCVT utilities to identify unnecessary files that
can be removed. See Run listOSM Utility (on page 22) and Run listCVT Utility (on
page 24) for information on setting up and running these utilities. You should also
keep the number of test releases on your system to a minimum.

Important! These times are approximate and do not consider outside influences. For
example, a DHCT on an RF cable with a poor signal might have to wait for the
carousel to cycle multiple times to completely read the file due to a high number of
bit errors. You should use these methods for estimating download times only to set
expectations as you prepare to perform the download. You should not use them as
absolute measures of download performance.
Run the Doctor Report
To help determine what the expected download times should be, you should run
To help determine what the expected download times should be, you should run
version 5.1.0.6 of the Doctor report. This report shows the ACCT (average or
approximate carousel cycle time), which you can use to determine a reasonably
accurate expected download time.

For CVT downloads, review the ACCT column for the boot loader carousel in the
Doctor report results. This is your best-case download time.

Note: The time shown in the ACCT column for the boot loader carousel is the time it
takes the carousel to cycle and does not consider "hunting time." If the DHCT has to
hunt for the CVT, the time can increase.
