SunOS 5.6 is quite old, but there is still fairly good software support = for it. Depending on the machine, it may be quite slow.

SunOS 4.x and FreeBSD are 'BSD' Unixes, while Solaris (SunOS 5.x and above) is a 'SysV' Unix. They are quite different in design as well as administration, but nearly all software will run equally well on either = OS. > > I spent an hour yesterday trying to find a SunOS command just to read = the > > CPU ussage (such as TOP does in BSD) and failed :-(..

Download and install top from http://www.sunfreeware.com=20 Or, use: mpstat show cpu statistics for each cpu iostat show system IO statistics ...and there are a few others.

That's really up to you to decide from a software point of view. Though as far as the hardware goes, there is no longer any support for sun4c hardware. > I dont know about netBSD, but OpenBSD has binary emulation for most > SunOS programs. > I'm running it on a Sparc IPX and it seems to work pretty well. >=20 > -mark NetBSD has emulation for SunOS 4.x and SunOS 5.x but you need to get the libraries from a SunOS host first, and you should also have licences. There is more info in the pkg/port doco for emul_sunos. As for multiple CPU's, you will get better balancing of load with Solaris, though you will still have CPU load issues with single-threaded application= s. Hope this give some insight.
