There is a tool/program that may be used (not available on releases prior to R310) that generates a spool file which shows how long the system spent in each of the IPL phases. To generate the spool file, type the following on the OS/400 command line:


	CALL QWCCRTEC

Press the Enter key.

It is rather handy for customers to run this occasionally or at least after IPLs following abnormal system ending (which forces the 2C40 cleanup) to provide data regarding how long the IPL stays in each phase. There are major differences between doing an IPL on a fast newer processor and doing an IPL on an older and much slower box. Major changes have been made during the various Version 4 releases to speed up the IPL process.
