Magento Cloud RipCurl Performance

genaker profile image Yegor Shytikov Updated on ・7 min read

I just read news about Magento 2 implementation of the RipCurl eCommerce website. It is always nice to check modern and fast e-commerce technologies at work. I just finished my K6 performance test toll optimized for Magento 2 performance testing. All Merchants on M2 are struggling with different kinds of performance problems especially during high load periods - Black Friday, Christmas, successful promotions or just successful business.

Percentile 95: 2.91s Time To First Bite

A 95th percentile is a number that is greater than 95% of the numbers in a given set. The reason this statistic is so useful in measuring data throughput is that it gives a very accurate picture of the maximum TTFB. This is a standard measure used in interpreting performance data.

Pretty good result as for Magento Cloud. 10 requests it can handle.

How about 20?

Throughput is not bad however TTFB performance is relay slow 2.5. Moving out from the Magento cloud usually speeds up TTFB 2-3 times. Sub-second TTFB without FPC possible if to use AWS Graviton 2 processor.

However, performance is more than the initial load time. That initial load time or time to the first byte typically accounts for less than 5%-10% of your time to the first interaction, a more meaningful performance metric.

The 90-95% after the initial content is loaded is due to poor front-end architecture. And even Varnish will not help you.
