Hi, everyone,
I really wonder how many queries per second a dns server can process
with what kind of hardware configuration.
I have got a dns server , SUN E450 with two 400MHz CPU, 4G mem, no
other application, dedicated for dns service, Runing bind 8.3.3
Now, it handles almost 1300 queries per second, and have used up 80%
of process power of one cpu , since bind8 is single-processed and
single-threaded , it can't use the two cpu at the same time, that means the
server has almost used up all cpu power this machine can provide for dns
service. So I had to face two choice: upgrade to bind9 or upgrade the
hardware, most probably the CPU .
But I recall a lot of people said that dns service needs very few cpu power ,
so Why a 400MHz cpu in my server can only support up to 1300 queries per
second?
Does anyone has got any idea, in generally , how much load could be
supported
with a workstation like this, or with what kind of cpu power can you handle
how
many load ?
Any inputs are welcome
sincerely
likun
