This sounds like its the mail server throttling "thing". Many servers, particularly those on shared hosting, limit the amount of email a server can send per hour to control spam risks. Your host should be able to tell you what you are throttled to. If you increase the 15 to say 60 you will be done in 2 hours (provided your host allows that many emails!) - **BUT** beware - that will result in a loop of 60 emails to send before someone sees a page... 60 may be OK, 600 would maybe not be.


Hi Calum,

thanks for the wealth of information. One point I didn't quite understand was " **BUT** beware - that will result in a loop of 60 emails to send before someone sees a page", does this mean that when event booking needs to send out 60 emails in 1 go, the website stops delivering web pages until the emails are sent?

My host have the server throttled to 600 emails per hour.

Regards,
D

What Calum was saying was that there might be a slight delay in displaying the webpage to your visitor as your server sends 60 emails as part of the page-request cycle. My guess is that the delay should not really be noticeable for the user at 60, but could become noticeable if the value was set really high.
You would just have to do a code-level test on your server to time how long it takes to send xx emails to know what kind of delay would be incurred (eg. write a php script to post start time to screen, loop 60 times over an email command to email yourself a bunch of emails, and post the end time to screen).

What he said!

Lets assume it takes 10msec to send a single email. Sending 600 will take 6 seconds. So the user who browses your site and triggers the sending will experience a 6 second pause. If you reduce that to 40 or 60 emails they experience a half second delay. Far less likely to close the window and try another site.

I'm guessing what the time lag for mail() is and there are too many variables on sites to even guess. But setting it at 60 mails per hour would get you done in 2 hours. You just need to know that 60 mails doesn't slow down that one user for 30 seconds.

Incidentally any other user accessing the site immediately after that first user will experience no latency. They will not trigger the script.
