For a properly written webapp, I doubt that you'll be able to measure much = difference in CPU performance, other than the increased likelihood of opera= nd cache misses when you have multiple active Servlet objects rather than j= ust one. There would be some increase in Java heap (and therefore RAM) usa= ge as well, but given enough real memory that's not likely to be an issue. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MA= TERIAL and is thus for use only by the intended recipient.
