If I remember history right, back in the 2.0.0 or 2.0.5 days there was a comparison of Linux, FreeBSD, and Solaris x86. The Solaris results were unmemorable other than both Linux and FreeBSD usually beat it, but not always. Linux was faster than FreeBSD at small file tasks. Linux was faster than FreeBSD up to about 25 processes. FreeBSD cleanly scaled up to about 400 processes when Linux buckled at 100. By "buckled" I mean internal inefficiencies started to make additional processes more expensive to run than on a lightly loaded machine. Somebody at the time attributed this behaviour to Linux using a simple linear table to manage processes while FreeBSD used a hashed table. Think the above is somehow related to the Modern Urban Legend which claims Linux is a better desktop machine, FreeBSD is a better server, as at the keyboard Linux seemed faster than FreeBSD. -- David Kelly N4HHE, dkelly@nospam.hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
