[Pdns-users] PDNS performance comparison to BIND

[Jan Rudinsky]

Hello,
I have tested PDNS performance (configuration below). A zone transfer of 
100 000 records takes ~ 10 s using either MySQL or file backends.
However Bind can make it in ~ 1 s (file-stored records).

I have read the pdns manual chap.9 and tested the distributor-threads, 
cache-ttl and query-cache-ttl settings without a change in the performance.

How can the performance be improved?

Thank you for suggestions,

Jan
