A weakness of freebsd is its fussyness over hardware in particular
network cards, time and time again I see posts here telling people to
go out buying expensive intel pro 1000 cards just so they can use the
operating system properly when I think its reasonable to expect
mainstream hardware to work, eg. realtek is mainstream and common as a
onboard nic but the support in freebsd is poor and only serving
datacentres to shy away from freebsd.  If the same hardware performs
better in linux then the hardware isnt to blame for worser performance
in fbsd.
