I'm not sure who made the second claim, but I run a server farm. We were completely a linux shop until 2 months ago. We had been holding out for the 2.4 Linux kernel as our supposed saviour. 2.2.x had been plagued by VM issues for the last 9 months. Upon loading 2.4.0 (problems also persist in 2.4.1) we found the following: VM was still broken under extreme io and network load. Software Raid 5 was trashed - when trying to rebuild an array, it would eat your disk. This was fixed in 2.4.1 So we bit the bullet and began the move to FreeBSD. It was a fairly heavy learning curve (new init system, new packaging system, sysctl for tweaking, etc.), but we're getting there. In all testing so far, FreeBSD has out performed Linux HUGELY. A Linux box, dual PIII-500 with 512MB of ram was running a site. The load average on the box was around 6-7. The site has been moved to a single processor PIII-800, with 256MB ram running FreeBSD. Load is down to 3-4 at peak times. So maybe the design is poor in some way, but the real world results have been well worth the change for us !
