isn't lowlatency kernels a default in Linux distros (well, at least in

latency and bandwidth are opposing goals. server oriented (compute-based
or storage-based) systems want to have the highest possible bandwidth,
not
the lowest latency. generally, at least.
From what I hear, the throughput of for example linux-lowlatency on Ubuntu
is 10% less than with linux-generic. So, that would be bad for servers in
deed.
Also, it is said to use more battery power, but I have not seen any data
on both of these things, so I really have no sources on that.
I do know that kernel developers in Ubuntu aren't interested in using
-lowlatency configs over -generic ones for these sort of reasons.
