Hi,
thanks for your help.
I noticed that the requests of those non-exist domain
name disappeared yesterday. But the NXDOMAIN record in
named.stats keep increasing. ( see attachment)
I'm using BIND9.2.5 & BIND9.3.1 on two Solaris box,
each box has two CPUs installed. it's found BIND8.4.6
running on one CPU could reach the throughput of
BIND9.*.* running on two CPUs.
Could we improve server throughput or lower lower the
effect of those requests on NXDOMAIN?
Joe
