PeopleSoft SendMail performance issue

Hi,

I am trying to send email notifications in PeopleSoft Expenses. Sendmail and MCF Mail. Both iof these are taking 7 secs for each mail. If I am sening 1000 mails, program is taking 70 mins to send mails.

Could you please suggest, how can I improve the send mail process.

Please see the below highlighted timings.

11:21:25.818 0.000877 29: &RET = SendMail(&MAIL_FLAGS, &MAIL_TO, &MAIL_CC, &MAIL_BCC, &MAIL_SUBJECT, &MAIL_TEXT, &MAIL_FILES, &MAIL_TITLES, &MAIL_SENDER, ";", "Content-type: text/html;");

11:21:31.755 5.936880 30: If (&RET = 0) Then

11:21:31.756 0.001397 31: MessageBox(0, "Alert", 0, 0, "Email has been sent to Emplid:" | &emailIDsend | "Email ID: " | &emplidMail);

Thanks in advance.
