Hi, I'm currently in the process of selecting hardware for a FreeBSD system having the main task of collecting network statistics via MRTG or RRDtool. In addition the machine in question should be used to collect netflow statistics plus providing a web-interface for displaying them. To give you an impression about the workload to be expected: Currently the system is a dual Xeon machine with 3GHz-CPUs reaching work loads (top) of 7 to 9. Disk-IO btw is not the problem. For the new system I thought about a 4-CPU machine, 4GB RAM - with either 32- or 64-bit architecture. Here are my questions: o) Should I stick with a 32-bit architecture (i386) or go for any of the 64-architectures? o) Is FreeBSD 6.1 considered equally stable under the i386 architecture as under any of the 64bit architectures? o) Are SMP-systems with 4 CPUs supported in i386? o) Are SMP-systems with 4 CPU supported in any of the 64-bit architectures? o) Anything else to consider in this context? Thanks much in advance for any clue, -ewald
