LiteMage First Page View

Your Magento 1 store loads faster right from the first page view with LiteMage Cache

LiteMage 1.3 Delivers Ultimate Magento
First Page View Performance

There is a wealth of statistics ( 1, 2 ) pointing out the extreme impatience of online shoppers (conversion rates dropping 7% due to 1 second page load delays, 38% due to 5 second page loads, vast numbers of visitors abandoning sites that are perceived as slow to load, etc.).

For new store visitors, the first page loading speed is a critical factor in visitor retention. With an industry median of 7.25 seconds, and the so called “optimal” 3 second threshold, what kind of initial impression does a vanilla, non-cached Magento store offer new visitors? Let's have a look.

No Cache: LiteSpeed vs. Apache vs. Nginx

We set up identical hardware platforms* running a vanilla Magento store on LiteSpeed Enterprise 5, Apache 2.4 and Nginx 1.1.15**, and tested each setup with varying numbers of new, first time visitors. We measured the average first page load speed for each of the servers.

Average first page load time in seconds (lower is better)

While LiteSpeed Enterprise consistently outperforms the other servers (with 30% to 50% faster load times), as the number of concurrent visitors increases, performance becomes unacceptable across all three platforms.

* All tests performed with SSL turned on, PHP 7.0.12, and MariaDB 10.1.18 on CentOS 7.2 Digital Ocean Droplets running Magento with the following hardware specifications: 1 Core from an Intel(R) Xeon(R) CPU E5-2650L v3 @ 1.80GHz, 1GB of RAM, and a 30GB SSD. The server software used was LiteSpeed Enterprise 5.1.9 + LiteMage 1.2.3, LiteSpeed Enterprise 5.1.10 + LiteMage 1.3.1, Apache 2.4.24 + Varnish 4.1.3 + Turpentine 0.7.0, and Nginx 1.1.15 + Varnish 4.1.3 + Turpentine 0.7.0.
** We are not sure why in these test scenarios NGINX showed lower performance than Apache - if you have suggestions on tuning the NGINX configuration for better performance, please let us know.

Full Page Cache to the Rescue?

Common knowledge tells us that to speed up a Magento store we should add a full page cache extension, so we added LiteMage 1.2 to our LiteSpeed Enterprise configuration, and Turpentine 0.7.0 + Varnish 4.1.3 for both Apache and NGINX, and reran our tests.

Average first page load time in seconds (lower is better)

Interestingly, while the addition of LiteMage 1.2 significantly sped up page loads for LiteSpeed Enterprise (by over 40% vs. uncached LiteSpeed Enterprise) and widened the gap between our server and the others, the results also indicate that the Turpentine+Varnish solution did not improve the first page load speed, and in some cases worsened performance. To understand why, see "When Caching Fails" below.

When Caching Fails

So why did adding Turpentine+Varnish fail to speed up the first page load?

Using Turpentine+Varnish entails setting up a separate reverse proxy Varnish server that communicates with the Magento backend utilizing the Turpentine plugin. Visitors hit the Varnish front end, which then has to request the page content from Apache or NGINX running Magento. For established (repeat) visitors, the Magento session is already set up, and Varnish is able to serve the page from cache rather than executing backend code. For new visitors, however, a new Magento session has to be initialized, a new "form key" generated, and the private cache (for punched holes) needs to be populated.

This costly operation negates any performance gained from serving the majority of the page from cache. In our testing, the results would have been worse for the non-LiteMage solutions if the page had multiple holes to fill, as they would have executed the Magento framework initialization multiple times. Luckily (for our competitors), the page we tested had just one hole to fill.

On the other hand, LiteMage, our advanced cache solution for Magento, is engineered to minimize Magento core code execution. Unlike competing solutions, our unique ESI inline object technology employs a single backend call for complete page generation, and has allowed us to consistently outperform others (see 'Real User Performance vs. "Benchmarks"' below).

Real User Performance vs. "Benchmarks"

In all our tests, we present results that would apply to a real user visiting the store. While others have published "benchmark" numbers that show much better competitor performance, the best advice we can offer is caveat emptor (buyer beware): competing solutions like Turpentine have added special code which detects benchmark tools (using User-Agent signatures), and when a benchmark tool is detected, they skip calling the backend in order to make the first page appear to load fast. We consider this approach cheating, as it does not reflect real visitor experience and offers an unrealistically optimistic impression of performance.

While the LiteMage 1.2 first page load time was impressive, it still showed gradual deterioration when the number of concurrent users rose over 100. We thought we could do better.

A Real Solution

In our new LiteMage 1.3 and LiteSpeed 5.1.10 release, we implemented an innovative technique where all first page content is served entirely from cache, completely eliminating the need for backend execution, session creation and form key generation. And unlike competing "benchmarks", all Magento functionality is preserved, and real users see real, dramatic results.

Average first page load time in seconds (lower is better)

Your Magento stores now get the same lightning fast speed for first page load times as for subsequent pages, 0.25 seconds(!) in our benchmark testing environment. LiteMage 1.3 consistently delivers 10x better first page view speed than Turpentine, with no significant deterioration even at extremely high concurrent user numbers.

Sub-second page load is critical in visitor retention, and only LiteSpeed is able to deliver this level of performance for your Magento site.

GDPR Statement

LiteSpeed Technologies values your users’ privacy. Although our software does not directly collect any personally identifiable information from visitors to your site, LiteSpeed may still be considered a data processor, as user information may be temporarily cached and/or logged, as outlined in this document.


LiteSpeed Web Server, OpenLiteSpeed, LiteSpeed Web ADC, and related software may record IP addresses as a part of normal logging. An access log and an error log may record visitor IP addresses and URL visited. The logs are stored locally on the system where LiteSpeed server software is installed and are not transferred to or accessed by LiteSpeed employees in any way, except as necessary in providing routine technical support if you request it. This logging may be turned off through configuration. It is up to individual server administrators to come up with their own schedule for removing such logs from the file system.

Cache Solutions

Our cache plugins potentially store a duplicate copy of every web page on display on your site. The pages are stored locally on the system where LiteSpeed server software is installed and are not transferred to or accessed by LiteSpeed employees in any way, except as necessary in providing routine technical support if you request it. All cache files are temporary, and may easily be purged before their natural expiration, if necessary, via a Purge All command. It is up to individual site administrators to come up with their own cache expiration rules.

LSCache for WordPress

In addition to caching, our WordPress plugin has an Image Optimization feature. When optimization is requested, images are transmitted to a remote LiteSpeed server, processed, and then transmitted back for use on your site. LiteSpeed keeps copies of optimized images for 7 days (in case of network stability issues) and then permanently deletes them.

Similarly, the WordPress plugin has a Reporting feature whereby a site owner can transmit an environment report to our server so that we may better provide technical support.

Neither of these features collects any visitor data. Only server and site data is involved.

Support Services

Sometimes, when you request technical support, LiteSpeed may ask for login credentials to various areas of your site. You may refuse to share such credentials, however refusal may impact LiteSpeed’s ability to provide the requested support services.

Upon completion of a support ticket, LiteSpeed immediately deletes all login credentials you may have shared.

Any user data encountered by LiteSpeed is kept strictly confidential. We never provide your support ticket information to any third party without your explicit consent.
