I am trying to send mails using phpmailer and code is working fine. However when I see the CPU usage history in task manager I could see it is fluctuating rapidly between 0% to 100%. And RAM usage is constant around 4.65GB of 6GB.
I was able to send 500 emails in 15 minutes or so and I feel its bit slow because my CPU usage is fluctuating a lot, may be I am wrong in my assumption.
- Can anyone help me in optimizing max usage of my system and fasten the process?

Also I have created a column in table
email_sent
to check how many mails have been sent and avoid any duplication but the code is not updating the database and giving up! (so it is commented out below).<?php //this code sends mails in HTML format using emailids from database. It also sends attachment if needed. error_reporting(E_ALL); //error_reporting(E_STRICT); ini_set("display_errors", "on"); ini_set('max_execution_time', 30000000); //300 seconds = 5 minutes ini_set('memory_limit', '6500M'); //Maximum amount of memory a script may consume (128MB by default) date_default_timezone_set('UTC'); require_once('../class.phpmailer.php'); //include("class.smtp.php"); // optional, gets called from within class.phpmailer.php if not already loaded $mail = new PHPMailer(); $body = file_get_contents("contents.html"); //$body = preg_replace('/[\]/','',$body); $body = preg_replace('/IDontKnowWTFThisFunctionIsdoing/','',$body); $mail->IsSMTP(); // telling the class to use SMTP $mail->Host = "ssl://smtp.gmail.com"; $mail->SMTPAuth = true; // enable SMTP authentication $mail->SMTPKeepAlive = true; // SMTP connection will not close after each email sent $mail->Host = "ssl://smtp.gmail.com"; // sets the SMTP server $mail->Port = 465; // set the SMTP port for the GMAIL server $mail->Username = "myemail@gmail.com"; // SMTP account username $mail->Password = "password"; // SMTP account password //$mail->SetFrom ('myemail@gmail.com', 'me'); $mail-> From = "myemail@gmail.com"; $mail->FromName = "me"; $mail->AddReplyTo ('myemail@gmail.com', 'me'); $mail->Subject = "Subject"; @MYSQL_CONNECT("localhost","root",""); @mysql_select_db("database"); $startnum1 = 501; $endnum1 = 5000; //$query = "SELECT emailid FROM test WHERE email_sent = 0 Limit $startnum1,$endnum1"; $query = "SELECT emailid FROM test Limit $startnum1,$endnum1"; $result = @MYSQL_QUERY($query); echo "message sending in process"; while ($row = mysql_fetch_array ($result)) { $mail->body = $body; $mail->AltBody = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test $mail->IsHTML(true); $mail->MsgHTML($body); $mail->AddAddress($row["emailid"], $row["emailid"]); //$mail->AddStringAttachment($row["emailid"], "contents.html"); if(!$mail->Send()) { echo "Mailer Error (" . str_replace("@", "@", $row["emailid"]) .

'<br />'; } else { //$query1 = "UPDATE test SET Email_Sent= 1 WHERE EmailID= emailid Limit $startnum1,$endnum1"; //$result1 = @MYSQL_QUERY($query1); echo "Message sent to :" . $row["emailid"] .
