[Unbound-users] How can I check what is in the cache?

Hi,

Well my vm took almost a minute to generate 3.7million entries (199meg file) and that was doing a test of urls for about 5-6 hours.
Of course vm would be slower..  haven't tried it for a real server yet. 

VM using 2 processors with 2G ram.
Having, 
       num-threads: 2
  	so-rcvbuf: 4m
  	so-sndbuf: 4m
       msg-cache-size: 200m
       msg-cache-slabs: 4
       rrset-cache-size: 400m
       rrset-cache-slabs: 4
       infra-cache-slabs: 4
       infra-cache-numhosts: 100000



Regards,

Michael

Hello Andreas,

On my machine the dump takes 2.5 seconds, but I was never successful in getting it to contain more than 170k entries (as measured by lines in the dump).

Could you share what cache and memory related settings you've got, please?

Best regards,
Maciej
