Why are there 8-9 seconds gaps between queries ? Has anyone seen this
problem before ?
Wow. I've seen slow DNS before, but typically it is due to my
application not calling ::process() in a timely fashion in the stack.
Are you running HEAD from SVN or something else? The general idea in
reSIProcate is to always query the DNS, or use a cache. Later
versions of reSIProcate from SVN include a local caching nameserver
to assist with SRV server migration.
So, I guess you should:
a) check that you are calling process sufficiently.
b) let us know what reSIProcate codebase you are seeing this in.
