I am considering buying a dual PIII CPU to replace the single PII CPU from which I operate a high traffic website running FreeBSD, Apache, PERL and mysql. I have been unable to locate a place where I can get a definitive answer on whether FreeBSD can make decent use of dual cpu or even if a PIII is compatible (though I know it is, the info available is not current enough). If anyone can point me to explicit info on this I would appreciate it. I am also enclosing the current and upgraded configuration below in case anyone would hazard a guess at the performance improvement that FreeBSD might experience. I have tuned the existing system such that it has no swap or process failures but during peak hours on the net it still runs like a slug. Will this upgrade do any good with FreeBSD commensurate with the cost? A related but not identical question is whether FreeBSD usage of multiple cpus is sufficiently better than just using one fast cpu? Existing Configuration PII 300 Mhz CPU 66 Mhz BUS IDE Controller (6.4 MB UDMA) 128 MB RAM Planned Upgrade Dual PIII 550 Mhz CPUs on ASUS P2B-DS ATX 100 Mhz BUS SCSI Controller (9.1 IBM Drive) 256 MB RAM Thanks in advance.
