This is a test application based on Ruby-on-Rails, using Devise for authentication.
Performance of this application was tested by continuously sending requests to the server. Five url's were included in the test:
- index-page without cookie (black)
- create-account-page (red)
- reset-password-request-page (green)
- index-page with good cookie (blue)
- index-page with bad cookie (cyan)

- Ruby with lowest slow response-count (> 7ms): ruby-3.3.1 (82x)
- Ruby with lowest median* response-time: ruby-3.3.1 YJIT (1.51ms)
- Ruby with lowest standard deviation response-time: ruby-3.3.1 YJIT (0.36ms)
- Ruby with lowest mean* response-time: ruby-3.3.1 YJIT (1.5ms)
- Ruby with lowest memory use: ruby-3.1.3 (86Mb)
* Mean and median are calculated after warmup (x > N/2).
Boxplot showing ~99% of all measurements (sorted by responsetime)
Showing a single tested uri and the most occurring response-times after warmup (x > N/2)
Logged after a fixed interval of measurements (1,000). Each run is shown in a different color
These scatter-plots show the response time of individual calls as dots. Note that many dots may overlap each other.
Vertical blue lines near the X-axis indicate major garbage collection runs (of Run-ID 1, but only when there are less than 100 GC runs).
Same as above but focussing on the most ocurring response times. GC runs are not shown.
