<font size=2 face="sans-serif">After procrastinating for months, we finally
got around to rebuilding our application on the most recent stable version
of the COIN/Cbc sources. Our last update was around two years ago.</font>
<br>
<br><font size=2 face="sans-serif">We were very pleasantly surprised to
find a dramatic speedup in solving our typical problem mix. Problems
that used to run out of time (with a timeout set to 1800 CPU seconds) now
complete in just a few seconds.</font>
<br>

experienced such a marked improvement? Should we be ecstatic ...
or suspicious?</font>
