Nothing in LimeSurvey can explain such difference .
BUT : What LimeSurvey do :
1. Make the email body/subject …
2. Tell to the system (mail/smtp …) to send the email
3. Wait for answer (OK/Not OK)
4. Got to 1
If you use mail function : the 2 to 3 take less than 0.01 seconds. If you use smtp fucntion with a remote server : it can take a lot of time.
With mail function : MY server receive the email and put it in "waiting list", and send it … sometimes some hour after (when i send 10 000 mail). Because some server (orange/wanadoo for example) don't accept more than one email by second from the same server …
