This is true. But in practice, pretty hard to measure. It affects connection time. In fact, many areas in the kernel are done with some expect usage. For example UDP won't scale well if you are using many many UDP services. Most linux box only have a few, so using a linear search for every UDP packet getting in is acceptable. Now, if you have several vservers each one having several UDP services, then the linear search may hit. Have you withness/measure any slowdown, between a vserver running on a quiet box and the same box without any vservers running ? --------------------------------------------------------- Jacques Gelinas <[EMAIL PROTECTED]> vserver: run general purpose virtual servers on one box, full speed! http://www.solucorp.qc.ca/miscprj/s_context.hc
