I am emailing off my server and its really slow. I think the problem is my logic, not the code. Current speed is about 30-40 emails per minute. I need to get it up to at least 175/min but I was really hoping for more like 700/min. The server is a Dual Hexa-Core 2.4Ghz with 32gb ram and dedicated to only this task. All server reports show low resource usage. The logic flow is like this: 1. Get email content. 2. Loop through records in database. 3. Check record against some other tables (ie unsubscribe table) 4. If record checks then send email by file_get_contents passing all the email content through get variables. 5. Other script is basic email script. See below: <?php //GET VAR INPUT $to = htmlentities($_GET['to']); $friendly_from = htmlentities($_GET['friendly_from']); $email_from = htmlentities($_GET['email_from']); $subject = htmlentities($_GET['subject']); $text = htmlentities($_GET['text']); $html = $_GET['html']; $html = '<head><title>' . $subject . '</title></head><body>' . $html . '</body>'; //SEND EMAIL # Setup mime boundary $mime_boundary = 'Multipart_Boundary_x' . md5(time()) . 'x'; $headers = "MIME-Version: 1.0\r\n"; $headers .= "Content-Type: multipart/alternative; boundary=\"$mime_boundary\"\r\n"; $headers .= "Content-Transfer-Encoding: 7bit\r\n"; $headers .= "Reply-To: " . $email_from . " \r\n"; # Add in plain text version $body.= "--$mime_boundary\n"; $body.= "Content-Type: text/plain; charset=\"charset=us-ascii\"\n"; $body.= "Content-Transfer-Encoding: 7bit\n\n"; $body.= $text; $body.= "\n\n"; # Add in HTML version $body.= "--$mime_boundary\n"; $body.= "Content-Type: text/html; charset=\"UTF-8\"\n"; $body.= "Content-Transfer-Encoding: 7bit\n\n"; $body.= $html; $body.= "\n\n"; # End email $body.= "--$mime_boundary--\n"; # <-- Notice trailing --, required to close email body for mime's # Finish off headers $headers .= "From: " . $friendly_from . " <" . $email_from . ">\r\n"; $headers .= "X-Sender-IP: " . $_SERVER[SERVER_ADDR] . "\r\n"; $headers .= 'Date: ' . date('n/d/Y g:i A') . "\r\n"; //Mail it out $response = mail($to, $subject, $body, $headers); //RESPONSE (Success = 1, Fail = 0) echo $response; die(); ?> The entire thing runs on a cron job every minute checking with a lock to prevent multiple instances as the file usually executes for about 5 minutes. I have tried turning off parts of the code and retesting such as many of my database look ups but as you would expect they optimize by like 1% or something very little like that. The thing that takes a long time is the actual sending of the email. So how to get that to go faster?

My web-page loops through and echoes all 50,000 entries from a several-column mySQL database (part number, price, description, etc.). It is tedious for me, because It takes about a full minute for my browser to completely load it. I had an idea: Use "ob_start" at the beginning of the script, and insert an "ob_end_flush()" assertion in my "while" loop to get executed every 50 loops, like this: <?php ob_start(); ## access big mySQL database and output it to browser $i=0; while ( $a_row = mysql_fetch_assoc($result) ) { # echo output to browser if($i %50 == 0) { ob_end_flush(); } } ?> That cut the time down from 60 seconds down to about a second and a half. The problem is, the results are goofy (several mySQL rows missing, didn't get output to browser). Is there a better way? Or, am I on the right track? And, if I'm on the right track, what can I do to fix this? Thank you.

So just to preface this, I have been part of two operations (one as developer, one with a 3rd party company developing) where the business was forced to cease due to difficulties in database load balancing and lots of people lost lots of money. I am talking about big data and high performance needed at the same time. So for my new project, I am going to try and design it around having a forever expanding infrastructure of servers but that means setting it correctly from the beginning. I have put together some ideas for possible ways to split the database load across multiple servers. Any input to which idea(s) are best would be great so I know which to explore further. Also any relevant info on this type of thing would be helpful as this is the first time I am personally doing this. Thanks!

I need help with performance improvement of this script. Script is working fine, but it's quite slow. It loads a lot of data, around 200.000. I am using paging to speed it up, but it's still slow. Can you give me any guide lines how to speed it up or to optimize? //Početak paginga if (isset($_GET['pageno'])) { $pageno = $_GET['pageno']; } else { $pageno = 1; } // if $upit11 = mysql_query("SELECT id FROM kalkulacija_stavke WHERE id_kalkulacija = '$id_kalkulacije' AND kataloski_broj NOT LIKE '1%'") or die (mysql_error());

} // if $limit = 'LIMIT ' .($pageno - 1) * $rows_per_page .',' .$rows_per_page; mysql_query( "SET NAMES utf8", $veza ); mysql_query( "SET CHARACTER SET utf8", $veza ); if($_SESSION["checked"] = "checked"){ $upit = "SELECT kalkulacija_stavke.*, kalkulacija_zamjene_staro.ne_koristi_se FROM kalkulacija_stavke LEFT JOIN kalkulacija_zamjene_staro ON kalkulacija_stavke.kataloski_broj = kalkulacija_zamjene_staro.kataloski_broj_stari WHERE id_kalkulacija = '$id_kalkulacije' AND ne_koristi_se = '0' AND kataloski_broj NOT LIKE '1%' ORDER BY kataloski_broj ASC $limit";

Hi everyone! In my google Adsense page... i have the performance of my website as optimization revenue, website health... In the website health, i have this message: Reduce the size of the above-the-fold content i read a bit, and i saw that i have to use asynchone code : like facebook like button, google+ button, adsense code..... so i have made the change for asynchrone code.. But what about my CSS and my JS? I use <script src="/js/libs/modernizr-2.5.3.min.js"></script> (because i'm using HTML5) and <script src="//ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script> on ALL pages of my website. for Reduce the size of the above-the-fold content, what do you suggest to me for CSS and JS code? Thanks to all!!! have a great night!

I am writting a document management application which is running a very large if statement, similar to if(($filetype == jpeg)||(filetype == gif)){ $type = "Image"; }elseif... and so on it's about 180 lines. The Problem is I can do it in an array as well, an array will be less code. but is it faster? I am talking large amounts my software knows 600 different extensions with 380 different icons assigned to the file type. I need to know for performance which is faster? and array or an if and ifelse? If I could get assistance that would be good. I would test it myself but rewritting as array for no reason if an if statement is the faster of the two. Thanks.
