i agree it is worth a try. all the pieces of puzzle are already in place in 2.4.x &
glibc 2.2.x. we have an ongoing implementation in Canberra Au, that can give light to
this >=130K users ( SALT clustered). whatever the results would be ill post it on the
list. that we'll know if Intel cant really scale...
cheers,
