That seems odd to me. I am not seeing (and haven't seen) any delays
like you are reporting. You might try turning up the logging
$ pfexec cupsctl LogLevel=debug2
and taking a look at the error log (/var/log/cups/error_log). It will
give you some idea of what's going on and when. There are a bunch of
things that could affect performance. Is you system resource starved?
Are you using and nameservers (NIS, DNS, ...) that it may be having
trouble contacting?
