We've found the advice from Technical Note #2, a very unsatisfactory way to resync from being offline mainly because of the time it takes to run p4 diff throughout your entire client mapping. In a directory with 164 files, we modified 1 file. It took 9 seconds for p4 diff to determine that file changed (and that it was that fast because we only ran p4 diff on that directory). However, if we were to run it at a higher level, such as //depot/..., it would take about 5 mintues. So, I was wondering how other people have implemented a way to resync from offline.
