    If you don't do much traffic you can just upload the video to your webserver.

    Tim Vereecke got a reaction from isabella in FOSDEM 2024 - Revive Adserver Performance Talk   
    On February 4th 2024 (Noon CET) I will present at FOSDEM 2024; the topic is about how I used Revive Adserver to improve privacy and Web Performance.
    Maybe I will see you in Brussels? Or if you are interested there is also a live stream

    From Google AdSense to FOSS: Lightning-fast privacy-friendly banners
    I run [link removed], the largest and fastest scale modeling website in the world. As such, I need a fast and privacy-aware advertisement solution to best serve my user base.
    5 years ago, just before GDPR became applicable I decided to replace my existing Google AdSense solution. While easy to set up, AdSense and other vendors were in hindsight too slow or not meeting my privacy expectations.
    The cornerstone of the new architecture became the popular, free and open source (GNU GPL) Revive Adserver (formerly known as OpenX). Without leaking information, Revive Adserver allows me to serve targeted ads without degrading Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS) or other Web Vitals.
    In this talk you will learn about my design choices as well as interesting techniques and best practices to serve and monitor banner ads performance.

    Tim Vereecke reacted to steve bullman in Asynchronous JS or Javascript invocation code?   
    I was advised by my developer to use Asynchronous JS for display ads, but it is considerably slower than using Javascript method. Whilst Javascript loads instantly, there is a clear second delay if I use JS. Is there a way to improve this?

    Tim Vereecke reacted to utrenkner in Banner type: PHP   
    I was thinking of something very similar*, but have not yet found the time to try it out. One possibility would be using an Iframe. But of course, this also adds another request.
    * My use case is for WordPress: We cache the rendered pages, but I would like to include a block similar to yours to show featured or most-read posts (I know there are plugins for this, but most of them do not work properly with caching. Delivering these recommended blog posts via Revive would solve several problems in our setup).
     
    PS: Funny to meet you here, I have been following you on Twitter for some time, due to my interest in web performance

    Tim Vereecke got a reaction from utrenkner in Banner type: PHP   
    Hi,
    Is there a banner type which supports executing PHP to render the banner HTML dynamically?
    Current state
    I currently have an HTML banner which populates dynamic data like below (4 dynamically picked products, with up to date pricing).
    The JS code to fetch and display the data runs client side. Although it works like a charm it does involve multiple requests.

    Question for future state
    I would like to execute this logic server side and have Revive return the server side rendered HTML by executing PHP (read from database).
    Is it possible? And what is the best approach to do that? 
    I tried looking for an existing plugin and or forum post discussing this; but failed to find it?
     
    Thank you for your guidance!

    Tim Vereecke reacted to Stephanie in Lazy Loading in revive   
    You need to modify the delivery file you use (asyncspc.php or afr.php)
    Search for :
    $imageTag = "$clickTag<img src='".htmlspecialchars($imageUrl, ENT_QUOTES)."' width='$width' height='$height' alt='$alt' title='$alt' border='0'$imgStatus />$clickTagEnd";
     
    change it to :
    $imageTag = "$clickTag<img src='".htmlspecialchars($imageUrl, ENT_QUOTES)."' width='$width' height='$height' loading='lazy' alt='$alt' title='$alt' border='0'$imgStatus />$clickTagEnd";

    Thank you for sharing!! Just to clarify, on line 3436 I added this:
    $imageTag = "$clickTag<img src='".htmlspecialchars($imageUrl, ENT_QUOTES)."' width='$width' height='$height' alt='$alt' title='$alt' loading='lazy' border='0'$imgStatus />$clickTagEnd";
    Revive coders...are you listening? This is an extremely simple solution to speeding up serving banners with your software, can you please add this to the source code?

    Hi,
    For those interested in performance, after modifying asyncspc.php and adding native loading=lazy (supported in Chrome/FF) to the $imageTag I gained 3-4 points in Google Pagespeed Insights.
    When scrolling down the Revive banners are loaded well before they appear in the viewport.
    Hope this helps

    Tim Vereecke got a reaction from Josh in Remove fl.js for better JS performance   
    Hi,
    Background:
    All the banners I server are either images or HTML and there is 0% chance I serve flash.
    While doing a performance review of my JS code I noted the standard Revive JS code (served via /asyncjs.php) contained a whole section of JS referencing ShockwaveFlash.ShockwaveFlash
    Checking the asyncjs.php source I see it includes a reference to a required flash config file (fl.js in the /www/delivery folder)
    require __DIR__.'/'.$GLOBALS['_MAX']['CONF']['file']['asyncjsjs']; require __DIR__.'/'.$GLOBALS['_MAX']['CONF']['file']['flash']; I currently commented out the inclusion of the fl.js so the JS is smaller. All seems to work fine.
    Results
    asyncjs.php goes from 3.6KB to 2.0Kb when transferring over the wire (GZIP). (not massive, but with Chrome never slow mode, you only have a certain budget of JS available. Saving 1.6Kb here can help to stay under the 500kb limit) 9883 bytes to 42993 bytes in unzipped format. (this is less JS code to parse/execute. Read The Cost Of JavaScript In 2018 for more details https://medium.com/@addyosmani/the-cost-of-javascript-in-2018-7d8950fbb5d4)   
    My 3 questions for the community are?
    Do you know any side effects of removing the fl.js inclusion?  Are there better options than commenting it out? Are there other JS optimisations you are aware off? Thank you

    Tim Vereecke got a reaction from andrewatfornax in Statistics by campaign type   
    Hi,
    I'm interested in overal statistics by campaign type. (eg. Remnant, contract, ...)
    I want to see Revenue/Clicks/Impressions for all my contract campaigns without the noise of remnant campaigns.
    I want to see the evolution of total remnant impressions compared to all impressions. 
    Is this possible today?
    Thank you.
    Tim
     
     
    My own reply:
    Sometimes you find the answer yourself the minute after posting the question. All my internal remnant campaigns belong to the same advertiser. As there are plenty of reports available by advertiser it is straight forward getting the info.

    Hi Tobean,
    I was surprised to see there is a new GDPR release giving extra control on the OAID cookie since yesterday evening
    https://www.revive-adserver.com/blog/revive-adserver-v4-1-4-released/
    Hope this helps. I'll try and to the upgrade this weekend.

    Tim Vereecke reacted to tobean in Cookies (new EU legislation)   
    Hi!
    in the future it must be possible to opt out from setting cookies in Revive adserver. In the actual release cookies seem to be set for one year. In the config file I found the option
    permCookieSeconds=31536000
    Is it possible to reduce this time to 1 hour (or for the actual browser session)? Or what is the reason that the cookie lives for 1 year?
    Or can I even set permCookieSeconds=0 to get rid of all cookies? I know that some feature will no longer work in this case (e.g. display the same banner more than once).
    It would be nice to get an anser from Eric or another admin because Revive will no longer be legal when the new legislation comes on may 25th.
    Best regards
    tobean
