@ruhrscholz @fennix Can you maybe describe a benchmarking scenario?
I usually don't use the webfrontend that much but when I do it appears to be reasonable fast.
I just logged in, opened a random directory and opened a docx file with only office within it and it took 4.2s, 1.8s and 2.1s (all measured only once).
If your setup yields similar times we just have different definitions of slow, otherwise you could probably still optimize sth (no clue what though).
