Magento Enterprise Edition (EE) 1.13 Benchmarking Guide

Contents

Customer Needs and Expectations

The focus of the Magento Enterprise Edition 1.13 release is performance and scalability. The benchmarking results presented here demonstrate that we have addressed the following concerns:

  1. The eCommerce landscape is changing, and merchants must provide customers with an online shopping experience that meets their performance expectations
  2. As merchants grow their businesses and increasingly larger enterprise merchants are adopting Magento, Magento Enterprise Edition must scale to handle increased traffic volume and larger catalogs

Magento's Plan

We identified the following areas for enhancement in Magento Enterprise Edition 1.13:

What Magento Accomplished

Magento Enterprise Edition 1.13 delivers the following improvements over Magento Enterprise Edition 1.12:

Multi-Node Deployment Topology

Before we introduce you to the benchmarks, an overview of our multi-node benchmarking facility is in order. We started with a basic multi-node cluster with load balancer and caching and separate DB node, and installed Apache. This is a familiar hardware configuration for the Magento developer community. Once provisioned, we installed both Magento Enterprise Edition 1.13 and Magento Enterprise Edition 1.12 on the cluster to compare their performance.

This is a representation of the multi-node Magento Enterprise Edition 1.12/1.13 installation used for performance testing. It consists of four physical nodes, three of which are virtualized.

We used HP ProLiant SL230s Gen8 servers with 8x16GB DDR3 and 2x Intel Xeon E5‐2660 CPUs for our benchmarking.

We used a physical disk of a usable 1.2 TB managed by a RAID10 controller. The load balancer we used is nginx.

The cluster resides in our Las Vegas data center, connected to the Internet via a gigabit connection. We tested the cluster using the popular Gatling suite from our engineering offices in Austin, TX.

Software Components

Scenarios

This section presents the merchant scenarios we simulated for our testing. These scenarios are based on real-world experience and industry standards with respect to shopper flows and catalog sizes.

Shopper Flows

We used real-world, established eCommerce metrics to simulate shopper flows.

Catalog

The catalogs we simulated also reflect real-world, established eCommerce experience.

Target Merchant Profile

The simulated merchant profile we benchmarked against represents the profile of our enterprise customers. We established these metrics based on the day-to-day experience of large merchants operating a successful eCommerce business. Again, we used what we consider to be a typical hardware and software configuration.

Benchmarking Results

These benchmarks were generated during extensive testing of our multi-node configuration running Magento Enterprise Edition 1.13 described above. Our configuration was modeled after what a commercial hosting partner would put into production, and the results reflect accurate gains over Magento Enterprise Edition 1.12.

The duration of the test sessions is 72 seconds, which significantly stresses the multi-node configuration.

Incremental Re-indexing

In Magento Enterprise Edition 1.12, any change to a product would result in a full re-index. Magento Enterprise Edition 1.13 introduces a new feature--incremental re-indexing. With incremental re-indexing, only those items that were changed or added will be re-indexed, reducing the processing time to a fraction of what was required before.

Take the example of a merchant with a catalog containing 500,000 products. In Magento Enterprise Edition 1.12, any change to a product would result in a full re-index operation. In Magento Enterprise Edition 1.13, incremental re-indexing means the merchant will only re-index items that were changed. The test focused on measuring the improvements provided by the incremental re-indexing feature in Magento Enterprise Edition 1.13. The table below compares improvements to common admin actions, such as changing a product description, prices or inventory.

Full Re-indexing

As part of the benchmarking effort, we also measured the improvements in the full re-indexing feature on Magento Enterprise Edition 1.13, where indexing a 500,000-item catalog was 53% faster than Magento Enterprise Edition 1.12. Faster re-indexing means less load on the system and that changes to the catalog propagate faster to the storefront.

Individual Re-indexers

The Magento Enterprise Edition 1.13 indexer component contains a number of individual indexers such as Product Flat Data and Product Price. When a Magento admin changes the price of a product, it is only necessary to execute the Product Price indexer for pricing changes to propagate to the front end. The completion times of these individual indexers were measured in the benchmark environment for Magento Enterprise Edition 1.13 and Magento Enterprise Edition 1.12.

This section presents the results for full re-index completion times for the individual indexers in Magento Enterprise Edition 1.13 compared to Magento Enterprise Edition 1.12.

Page Load Times

When Magento Enterprise Edition 1.12 and Magento Enterprise Edition 1.13 were compared, with both running on our multi-node benchmarking configuration, Magento Enterprise Edition 1.13 loaded pages 65% faster than Magento Enterprise Edition 1.12.

Guest checkout and registered user checkout are two flows that are crucial to storefront operation. This section presents the results of page load time measurements for these two flows.

Guest Checkout Flow Page Load Times

In the guest checkout flow pages, Magento Enterprise Edition 1.13 provides a substantial decrease in load times over its predecessor, most of the time more than twice as fast.

Registered Checkout Flow Page Load Times

The bar chart below presents the improvements in page load times for registered checkout flow.

Page Views and Orders

In addition to page load times, the benchmark also focused on measuring throughput improvements, particularly page views per day and orders per day.

During our testing, which simulated a storefront running at peak hours, EE 1.13 executed 33% more orders and 31% more page views than Magento Enterprise Edition 1.12 on the multi-node benchmarking configuration. Notably, Magento Enterprise Edition 1.13 served 47K pages during the test run (10 minutes).

Observations

What we noted during the benchmarking tests:

Conclusion

Magento Enterprise Edition 1.13 was engineered for performance--and clearly delivers on the goal as measured by important metrics.

In addition, we have focused on providing these benefits without the need to upgrade existing hardware, improving your return on assets and investment.

Appendix

Page Load Times

This benchmark report presented analysis of the results produced by the Gatling load generator tool. In this appendix, you can see the actual results reported by Gatling. The results were obtained under the following test setup, which was designed to push Magento to its limit.
Concurrent session (users) 1000
Peak load duration 10 minutes
Session duration 72 seconds
CPU utilization 95%

CPU utilization is high because session duration was set to 72 seconds for the test. Session duration was set to a low value to increase the active load on Magento. A typical e-commerce site will see session durations of five minutes or more. Preliminary experiments by the benchmark team have confirmed that using a five-minute session duration reduces the CPU utilization to 50-60%.

Estimating the Number of Visitors

Gatling does not report the number of users that cycled through during the test. However, it is possible to estimate the number using the following formula:
