...mance measurement. One would expect the second version to be slightly (very slightly) slower than the first. But I am finding this is not the case! The second version is slightly faster. How can this be?

Andr?, are you quite sure you have it working? In this thread someone from Open-Xchange stated that no, Dovecot doesn?t have SMTPUTF8 support implemented, and the same response was given by another Dovecot developer last September (it ?is being considered? was the answer then, see https://dovecot.org/pipermail/dovecot/2018-September/112887.html). I am using LMTP to deliver mail to Dovecot from

Dear R-users, I am facing problem with integrating in R a likelihood function which is a function of four parameters. It's giving me the result at the end but taking more than half an hour to run. I'm wondering is there any other efficient way deal with. The following is my code. I am ready to provide any other description of my function if you need to move forward.
