Byte have an article in today's ServingLinux column which talks about the factors to consider when planning a new server. FreeBSD gets a mention: "Together with other algorithmic deficiencies of the Linux memory manager, this results in poor performance when memory is tight compared to, say, FreeBSD or Solaris. It is therefore imperative to give to your Linux server ample RAM to avoid the inefficient page scanner. ...As with other disk I/O it is mandatory to spread the swap spaces among as many disks as possible. Solaris, HP-UX, Irix, BSD and UnixWare will all automatically round-robin among available swap-spaces, even if added at run-time. Linux, will not round-robin if you don't stripe the swap-spaces among physical units by means of RAID 0 or 1." It's a shame they missed the obvious conclusion: instead of over-compensating in hardware to deal with an inefficient operating system, use one which can make good use of what you already have.
