I can see why webmin would be slow with an 18000 record zone file. 
Currently, it parses that entire file every time you open a page that 
does anything within the zone, and reading such a large file with Perl 
is going to take a long time..

Unfortunately, there isn't really any solution, except modifying 
webmin to add some kind of indexing or caching code for BIND zone files.
