Paragraphs

After examining the situation in detail, the PFLB team proposed a Quick Load Testing solution. It included a four-day load testing project carried out by PFLB together with Tynor’s in-house engineers using a powerful testing PFLB platform.

The solution provided test results and recommendations on what to improve to increase website performance. In addition, a month-long subscription to PFLB Platform included in the Quick Load Testing proposal allowed Tynor’s team to run more test iterations on their own when needed.

  • Test Environment Complexity
    Continuous performance testing requires realistic performance testing environments  that accurately mimic production conditions. This can be challenging to set up and maintain, especially for large-scale applications with complex architectures.
    • Basic is simpler, less sensitive to seasonality or long-term trends; good for metrics without predictable cycles.

  • Test Environment Complexity
    Consistently generating and managing test data is critical for accurate performance assessments. Without realistic data, test results can be misleading, potentially masking serious issues.

  • Start early. This way, you’ll have time to fix every bottleneck found while testing before high season starts. There are many tools to test your performance right now, including boomq.io.
  • Ask for qualified QA help to figure out the reasons behind test results. What is slowing down your system? Are the pictures in the mobile version too large? Is your video ad slowing down the TTI by 2? How many simultaneous users can shop? Is this as many as you expect on holidays, or less?
  • Don’t run tests during peak hours. You don’t want your customer to be in the middle of a transaction when the system freezes.

  1. Price and Value
    I calculated the cost per virtual user hour (VUH) whenever possible. This made it easy to see which platforms deliver the most realistic traffic for the money. For enterprise-scale scenarios, I also considered how pricing changes as concurrency scales up.

    Managing your own load infrastructure adds friction. I prioritized tools that provide hosted load generators in multiple geographic regions, so you can run tests quickly without worrying about servers.

Get seated and try to count how much it will cost you if your website crashes for mere 15 minutes, or if 30% of your visitors leave the app due to unexpectedly slow response. Are you sure your website or app’s performance is better than those of, say, Costco’s?

This is a fact
In 2021, Cyber Monday garnered $10.7 billion, which makes it 1.4% less than in 2020 (falling for the first time ever). However, it remains the biggest online shopping day of the year. Black Friday 2021 sales volume was $8.9bn, which is almost 20% more than the pandemic 2019, but down 1.3% from 2020.
