phpmailer time to send email

Hi all, i noticed that any table that has notification enabled to send email on edit for example, the time it takes to process the update regardless of the size of the email and the table column/fields,
there is a 5-6 seconds delaying on the page update and this is due to sending email using phpmailer.
is there away to make this faster?

That mostly depends on your mail server. You may try another SMTP server.
