Split things up when they get slow. There is no good guide to when they will get slow because each system is different and has different load patterns. > different tasks (like network I/O, disk I/O, cpu)? For instance, Machines with Intel CPUs will beat almost anything for integer math, will perform OK for floating point math (which is fine as you hardly ever need it for an ISP), and will perform quite well for network and disk IO. If you do some benchmarks expect the latest Intel/AMD-based machines to outperform your Sun and your Mac on every test. IO is one area that PCs can really stand out. Software RAID on Linux with ATA-100 hard drives can easily outperform Sun hardware RAID arrays costing 100 times more money. Another issue is that of reliability. If something dies and you go off-line then you lose money! Use RAID for all hard drives. Wherever possible have several almost identical machines so that you can swap parts when things go wrong. Having a Sun and an Apple is a bad idea IMHO. If one of them breaks you can't easily get replacement parts. With PCs you can have three identical PCs so if the most important machine dies you can swap parts with less important machines. -- http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/projects.html Projects I am working on http://www.coker.com.au/~russell/ My home page
