Load on server?

[Dr Zoidberg]

At present we have an External DNS server that doesn't service requests
directly but just provides updates to a commercial DNS provider once an
hour. We have about 40 of our own domains on there and about 400 records so
its under very little load.
We may soon be managing DNS for a number of other companies and will be
using the same arrangement where our server hosts the Primary zone files and
feeds updates to a commercial DNS provider.
Given that its a lowly PIII 450 with 128mb RAM (soon to be 384) can anyone
suggest how many zones it could host before I notice any real load on it.

A billion or so if nobody ever requests a record from them.

Seriously, sizing a DNS server isn't a science, you can't say that X
many zones fit on Y many megabytes. In general, long before you
overload your DNS system, you'll replace it because the hardware is
obsolete.

Thats what I thought.
We have the budget for a new server but there seems little point in spending
the money on something that just sits there. I'll keep it as is and find
something else to upgrade. :0)
