kzonecheck detect and support multiple cores
Description
We use kzonecheck
to validate large DNSSEC-signed zones. I noticed that on a multi core processor (eg 16 cores) always only one cpu is used. I guess, validation time could be speed up a lot if all available cores would be used.
I would find it useful if kzonecheck
could either detect the number of cores and automatically use all available cores or a argument switch could be provided where the user can specify a specific number of cores/threads to use. For operations such as signature verification this should improve the run time a lot I guess.
