Judging from the profiler report, you did not collect enough number of CPU samples. I recommend to keep the profiler running for at least 10-30 seconds when trying to profile typing latency. Also, note that running M-x profiler-report second time will _not_ reproduce the previous report, but instead show CPU profiler report between the last invocation of profiler-report and the second one. I recommend to do the following: 1. M-x profiler-stop 2. M-x profiler-start 3. Do typing in the problematic Org file for 10-30 seconds 4. M-x profiler-report (once!) 5.

The above steps should be the first thing to try and they will likely reveal the bottleneck. If not, you can go back to genetic bisection. I do not recommend manual commenting/uncommenting parts of you large config. Instead, you can try https://github.com/Malabarba/elisp-bug-hunter. But only if CPU profiling does not reveal anything useful. Best, Ihor
