I've run some benchmarks using the basic_workflow.t's selenium test, following the same scripts and protocol as https://wiki.koha-community.org/wiki/Benchmark_for_16.11
Script's adjustments (to use KTD instead of KohaDevBox) and results can be found at https://gitlab.com/joubu/koha-misc4dev/-/commits/benchmark_16.11-20.11
The 2 main graphs are attached to this bug report.
We clearly see a worrying increase of the time execution between 19.05 and 19.11.
I have first focussed on checkin, do some profiling and came to the conclusion that it was caused by ES not updating its index async.
A first step has been submitted on bug 27344.
Early feedbacks and comments welcomed!

I can't speak to Elasticsearch but it would be interesting to see graphs for "add items" and "search".
