The August Gomez Performance Index for E-Retailers finds little change at the top positions for both response time and availability categories. The benchmarked average for response time for e-retail transactions was 22.18 seconds and the average availability measure was 96.72%. As e-retailers rise or fall in their rankings each month, indications of performance impacting events can be seen.

Response Time Summary
The benchmarked average response time for retail transactions saw an increase that pushed response times to more than 2 seconds slower than in July (20.16 seconds). Most of the retailers maintained their rankings from the previous month, but two retailers seem to have made site changes that have significantly slowed their sites’ response times and impacted the benchmarked average. Most retailers saw a minor increase, which may indicate a heavier shopping load over the month.

Success Rate Summary
Success rates for August showed a slight decline over July’s benchmarked average (from 97.44% to 96.72% availability). Many sites, however, greatly improved their availability.

Many of the retailers below the benchmarked average for availability have been having issues with site changes. In addition, several of the sites have shown to be having trouble with their DNS entries, their global load balancing solutions, or just have very content heavy sites (having objects larger than 1 megabyte).

Most noteworthy was a decision made by Gap Inc. made to completely turn off its online store in the middle of August as it prepared for the fall shopping season.
