Last year we found ourselves CPU constrained at peak hour and undertook a series of initiatives to save it.
The metric we used to decide whether a particular initiative was worth taking - which did not pretend to be other than a very rough guide - was 1p (0.01 pounds UK) per CPU second. It's not a lot but there are 24 * 60 * 60 * 365 seconds in a year so each engine is doing £300k worth of work a year, by this reckoning. ((Of course we don't actually pay any less if we don't use an engine all the time, but the point was to defer upgrading, which we successfuly did.)) ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
