DNS performance issues

[lawrence.a.kravets at us.arthurandersen.com]

I have some quick performance questions.

We have a Sun Ultra 5  Sparc 2I  270mhz with 256mb of mem.

We are seeing massive performance issues of this box that provides
name service for 10,000 users.  Should this Sun box running Solaris 2.6 and
only running Bind 9.1.0 be able to handle the following load.  Below is a
snapshot of 1 hour.  Do these numbers seem high?  Does anything really stick out
 as
abnormal?


          Per Hour        Per Min        Per Sec.
