How many minutes (e.g.) does it take for exercise to exert the increasing effect on synovial fluid significantly, and when the effect reaches it peak?
Dear Benedek, maybe this paper is helpful for the topic:

Eur J Appl Physiol 2019;119(11-12):2401-2420. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6858392/pdf/421_2019_Article_4232.pdf
Cartliage deforms quite quickly within minutes under load. So I expect that synovial fluid starts increasing immediately, how long it goes on for I don't know. It's a good question as there seems little good evidence on how joint metablism changes with time and how long there maybe an increase in synovial fluid. I suppose it must depend on forces and repetition of loading and the intrinsic quality and age of the cartlaige. Some help here, but doesn answer the question.

10 min for a significant effect on athletes performance and after 20 min it will be at their peak.
This answer has given according to exercises performance enhancement due to warm up our body and increase circulation surround the joints, muscles, and other tissues ready to use for the performances.
