    Benchmarking LSCache for Drupal

    LiteSpeed Cache Module for Drupal Benchmarks

    We’re back with more benchmarks! This time, we’ve put our new LSCache module for Drupal 8 to the test. We compared LiteSpeed Web Server with LSCache, Apache with Varnish (Cachewall), and Apache with System Cache.

    Our testing consisted of burst tests and load testing, both of which are explained in more detail below.

    The Results

    Benchmark

    The following chart shows how many requests per second each server + cache solution combination processed during our burst tests. The larger the number, the better.

    As you can see, LiteSpeed Web Server + LSCache outperforms both Apache + Varnish and Apache + System Cache.

    Load Testing

    The following graphs show the CPU and Memory usage during testing for each server + cache solution combination tested. For these measurements, a smaller number is better.

    LiteSpeed Web Server + LSCache consumed less memory and CPU than both Apache tests.

    Try it Yourself

    You can see the specs of our configuration and test environment below. Feel free to run the same benchmarks yourself and verify our results.

    These are the commands we used in all tests (Replace example.com/path with the location of your test subjects):

    Benchmark

    ab -n 10000 -k -H "Accept-Encoding: gzip,deflate" -c 100 example.com/path

    Load Testing
    LSWS+LSCache and Apache+Varnish:

    siege -c 100 -r 20 -d 6 example.com/path

    Apache+System:

    siege -c 100 -r 20 -b example.com/path

    NOTE: We used -d 6 instead of -b in two cases because we wanted to ensure that each server+cache was processing roughly the same number of transactions per second. The -d parameter allows you to specify a delay.

    Each test was run five times, and the average result was used for our graphs.

    Web Server Configuration

    Common settings for LSWS and Apache:

    • Keep-Alive ON
    • PHP 7.1.15
    • Zend OPCache ON
    • Max Connections 20
    • PHP Child 5

    Server API version:

  • Cache all of the Things with LiteSpeed

    Cache all of the Things with LiteSpeed

    Cache all of the Things: A LiteSpeed Cache Roundup
    You may be a fan of our LiteMage cache extension for Magento, or super enthusiastic about our WordPress cache plugin, but did you know that there is more to our cache story? Indeed. Chances are there is a LiteSpeed Cache plugin for your other favorite web apps, too.

    LSCache plugins, in general

    LSCache is a server-based caching module that is built directly into LiteSpeed Web Server. It saves static versions of dynamically-generated HTML pages in order to speed up subsequent access to those pages. In the beginning, LSCache was set up entirely through rewrite rules and configuration files. It required users to know a little something about their server backend, or to contact their hosting provider to set up caching for them. But more importantly, rewrite-rule caching is inflexible. As such, site owners had no ability to purge on demand, which meant they could only cache for a few minutes at a time, if they wanted to avoid serving stale content.

    Enter LiteSpeed Cache Plugins.

    LiteSpeed Cache plugins take the server-based LSCache functionality and give it a familiar interface, whether that be the WordPress Dashboard or the XenForo Admin Control Panel. Additionally, an LSCache plugin lets you define rules for managing your app’s cache, and then automatically updates the configuration files and rewrite rules on your behalf.

    By putting the LSCache controls into the web apps that site owners use every day, LSCache has become far more accessible and flexible. Site owners may now cache pages for far longer than a few minutes, and they may manage their caches with greater precision.

    As of this writing, LSCache is available in seven flavors! You are probably aware of one or two of these plugins. You may even be a power user. But why stop there? If you’re running all of your web apps on a LiteSpeed server, then you should take advantage of as many of these plugins as you can!

    LSCache plugins, specifically

    Cache all of the Things: A LiteSpeed Cache Roundup
    Every LSCache plugin is a conduit to the cache module of a LiteSpeed server, whether that be LiteSpeed Enterprise, LiteSpeed Web ADC, or OpenLiteSpeed. The server’s module does all of the work, while the plugin provides a simple way for a site owner to tell the server what to do. Because of this, most of our cache plugins have the same abilities. When there are differences, they are usually down to the abilities of the web app itself, or complexities involved in implementing a particular feature for that web app.

    Speaking of the abilities of the web app, LSCache plugins are unique among cache solutions because they have a connection to both the server, and to the app. A plugin can use that relationship to provide features that other cache solutions (or simple rewrite rules) can’t duplicate. We alluded to a prime example of this earlier: tag-based purge.

    Tag-based purge is a cache management tool that takes purge cues from events that occur within the app. For example, when a new post is created in WordPress, LSCache for WordPress tells the server’s LSCache module to purge every page that would be affected by a new post (i.e. the relevant category and tag pages, the home page, etc.).

    All LSCache plugins are free and open source. To learn more about the specific features supported by each, click the name of the plugin.

    Magento

    All content can be assembled from cache, even per-user, private blocks. Multi-store, multi-currency, and multi-user-groups are supported. There are two different versions of LiteMage available: one for Magento 1.x and another for Magento 2.x.
