I am surprised you have problems, 3000 clients is not a large
installation - some have 100,000 or more. Can you elaborate on the
scale of the problem, whether it's all the time or only at peak
times, what sort of hardware it runs on, whether you are doing
synchronous or async logging, ...
You will find threads discussing performance in the archives - with
one thread as recent as last week under the heading "DHCP performance
testing"
You might try correctly defining your subnets, because what you have
written isn't valid - it's possible that the mismatch between subnet
declaration and reality is causing the server to have to do more work.
