We are trying to increase our Apdex score, so when we perform waterfall analysis we observed different situations.
We discovered R (Request Start) and F (Time to first byte) takes very long time. Here I am sharing some examples from our research.
Where should we start investigating this situation to decrease R and F time. Do you have any suggestions ?
.NET Framework 4.7
Windows Server 2019
R: 1 second ?
F: 9 seconds ?
Resource Request JS: 9.5 seconds blocking ?
Same page request 30 minutes between them, first requst takes 6 seconds but the second one takes 18 seconds
R: 10 seconds ?
F: 16.5 seconds ?
R: 34 seconds ?
F: 34.5 seconds
Same request within a minute, first one takes 17 seconds second one takes 58 seconds
