When we do performance assessments for web applications and APIs running on HTTP Server (Powered by Apache) for i, one of the first things we do is enable a powerful Apache extension called mod_deflate. Just as zipping up files on your PC saves space and accelerates file transfers, mod_deflate compresses output from your server before sending it over your network.
Does it really work? My tests show a speed improvement of 10 to 50 percent!
You might have heard that the major browser vendors were planning to block port 10080 – the port used by Zend Server through ZS 8 (PHP 5.6). Firefox made the first move, then Chrome followed. We have been receiving support requests on this issue since April 2021. Why did the browser vendors block port 10080, and what can you do to get your site working again?
UPDATE: CommunityPlus+ PHP is now known as Seiden PHP. A modest but powerful utility “stole the show” during last week’s Lunch & Learn with Alan Seiden and Paul Tuohy. Packaged with CommunityPlus+ PHP, Seiden Group’s siteadd creates an Apache HTTP instance and a FastCGI configuration customized for your needs. In seconds, you’ll be able to launch a sample PHP page to test your new web instance.
When your site gets busy, your web server may need a configuration change to handle the load. We often start with the Apache web server’s ThreadsPerChild directive.
ThreadsPerChild controls how many connections can exist at once. Defaulting to 40, its value can be set in your Apache instance configuration file (for example, /www/zendphp7/httpd.conf):
Starting January 27, 2015, I’ll be giving three free Tuesday webinars:
All three one-hour webinars will be held at 14:00 Central European Time (CET). That’s 8 AM Eastern Standard Time (EST). The registration page includes a time zone converter.

Thanks to Torbjörn Appehl of Data3 (COMMON Sweden) for organizing these.
Join me for two events this week sponsored by COMMON, a Users Group:

This Tuesday, learn how to Let Your PHP applications fly on IBM i. Busy? You can attend while getting your work done, with three one-hour class segments separated by breaks.
“Our process now runs 30-50% faster, thanks to one tip from Alan’s presentation.”
—Mike Meszaros, Software Developer, Specialty Pipe & Tube
You’ll learn to quickly improve your application’s performance, including:
I’ll be there to answer your questions. What’s more, the presentation will be archived for 60 days so you can review the material afterward.
“Alan is the performance guru of PHP on IBM i. When we encountered unexpectedly slow queries and program calls, Alan showed us a configuration change that helped our application run 3x faster, creating happy users. Thanks, Alan!”
—Adam Chuk Shirley, PHP Developer, Sabel Steel Service
What: PHP on IBM i performance eLearning event
When: Tuesday, December 10, 2013: three one-hour segments with two one-hour breaks, starting 11AM and ending 4PM (ET).
Where: Online
Cost: $150 (but discounted to $99 through Friday, Dec. 6)
For the first time, I’m teaching how to Let Your PHP applications fly on IBM i, including how to configure Zend Server for performance, diagnose bottlenecks, leverage unique IBM i performance tools, optimize DB2 and the IBM i toolkit, and improve performance of front-end javascript, style sheets, and the like. You’ll come away with knowledge that you can use immediately to improve your application’s performance.

August 22, 2013: At NESTU (user group in Fairfield, N.J.): “At ease! Relax your neck-back-shoulders at the keyboard”: A special presentation from Alan to help computer workers (such as all of us) avoid repetitive strain injury and stay poised at work. Fun and unusual.
September 9-11, 2013: COMMON Fall 2013 Conference and Expo in St. Louis, Missouri. The Premier IBM i event. I’m presenting 5 talks on PHP and web performance.
October 7, 2013: Full-day, in-depth PHP on IBM i Performance Workshop, 9:30-4PM (PT) at ZendCon (the PHP conference). Register for both parts of this tutorial (room 6) for Oct. 7, and the full conference, which goes till Oct. 10, in Santa Clara, California. I’m presenting several talks on PHP for IBM i in addition to the full-day performance tutorial.

Tomorrow I’m presenting a new webcast, New PHP Toolkit from Zend and IBM: Open Source on IBM i, as part of System i Network’s free “Virtual Conference.”
Date: Thursday, April 5
Time: 11:15am ET
Registration (free): http://tinyurl.com/new-toolkit-20120405
Other presentations in the virtual conference include Jon Paris explaining why PHP is an excellent strategic choice on IBM i, two talks on mobile technology, and more.
I invite you to watch the webcast, ask questions, and learn more about the new toolkit.
Hope you can join me for “Web performance first aid,” a webcast for the COMMON user group. The webcast will be recorded and archived for future listenings as well.
The webcast is for COMMON members, so anyone wanting to hear it needs to join COMMON.
I based the presentation on my consulting practice that helps ensure high performance for PHP and Zend Framework applications on IBM i. Good performance is critical for customer acceptance of web sites and mobile applications.
