CASE STUDY
Overcoming Magento Slow Site Load Challenges with cWarmer
Client Overview
Our distinguished client, a key player in the US region, boasts an impressive annual revenue exceeding $15 million and draws in a substantial monthly traffic of over 1 million users. Despite their significant success, they faced a critical challenge – persistent slow-loading webpages were leading to potential customer loss. This issue persisted even with Varnish implemented, page load times extended beyond 15 seconds.
Challenge
The primary concern centered around slow-loading webpages, undermining user experience and hindering customer conversion rates. Despite the presence of Varnish, the pages took more than 15 seconds to load. The root cause was traced to an average of 20 daily cache flushes, leading to the clearing of the entire Magento cache. Due to this frequent cache flushing, almost every customer encountered a cache miss, causing performance issues on the site.
Our Solution
The highly efficient team of cWarmer experts swiftly identified the issue and implemented our expertise on best practices for cache flushing. With this approach:
- A drastic reduction in the number of cache flushes has been observed.
- The time between two consecutive flushes was reduced.
- High priority pages are kept warm, most of the time.
The client was enlightened about the crucial concept that Varnish’s effectiveness relies on the presence of cached data. By ensuring that Varnish consistently cached priority URLs, users could potentially receive responses within an impressive 0.02 seconds in real-time.
Significant Increase in Cache Hit Miss Ratio
cWarmer is a cache warming SaaS solution which operates external to Magento, intelligently identifying any invalidations. Generally, it acts as a pseudo user, requesting invalidated pages from the database in the origin infrastructure. As normal requests get cached, cWarmer ensures invalidated pages are cached before real-time users request them, fully utilizing Varnish’s potential.
cWarmer offers real-time tracking of Time To First Byte (TTFB) for URLs, detailed reporting, and a prioritization engine recommending URL priorities for post-cache flush warming. The user-friendly dashboard includes a special warming feature ensuring all important CMS pages are consistently warmed.

Magento and Varnish Utilization
Magento, being a heavy platform, provides Varnish as a solution. However, to fully leverage Varnish’s effectiveness, a cache warming solution is indispensable. In this case, cWarmer emerged as the market leader in optimizing Varnish and enhancing overall Magento performance.
Implementation and Progress
The implementation of cWarmer led to a monumental improvement in the client’s eCommerce performance. The substantial shift in the cache hit-to-miss ratio, from 17:83 to an outstanding 82:18, led to significant reductions in webpage loading times.

TTFB Achievements
One of the key performance indicators, Time to First Byte (TTFB). TTFB is the time taken for the first byte to reach the browser after a request has been sent. This indicator has seen remarkable achievements:
This client now boasts a TTFB below 100 milliseconds, signifying a phenomenal reduction from an initial TTFB of over 4+ seconds. TTFB, or Time to First Byte, represents the time taken for the server to respond to the initial request. This remarkable improvement underscores the effectiveness of cWarmer in optimizing server performance and reducing latency.
Conclusion
In conclusion, cWarmer has proven itself as a pivotal solution for leading ecommerce platforms, significantly enhancing their performance optimization capabilities. By dramatically improving the cache hit miss ratio and reducing Time To First Byte (TTFB), along with boosting overall site performance, cWarmer establishes itself as an essential asset for ecommerce businesses aiming for peak performance.
