Hi, as you all know we had to replace the usage of the org.json library due to it's license (see SLING-6679). We decided to go with Apache Johnzon as the replacement.
Now as most of the work is done I did some performance testing, mainly of the json get servlet, rendering a 2k json response requested by 50 clients in parallel. Unfortunately it seems that this library is causing a significant performance degradation. I noticed json responses to be between 15% and 20% slower. I can't explain what is causing this as all we do is simply write out json. So I went ahead and did a quick test by replacing johnson with jackson and interestingly, this one is in the same range as org.json, slightly faster even. Given this, I seriously think we should not use johnson but switch to jackson. As we have identified all the places, replacing is not one of the nicest tasks, but it should be doable within a short time frame. WDYT?
