Hi Jasper, Welcome to the community. I'm glad to see another organization beginning to adopt Fineract CN. The wallet use case is the primary one we're trying to advanced as a community initially around Fineract CN so thank you for your transparency and willingness to collaborate on list. I'm looking forward to learning more of what Apollo is building and how we can assist you in contributing back to the upstream, and joining the concurrent working groups we have going around wallet requirements and performance and scalability.
I'll try to flag this thread to some of the others in the performance and scalability working group to give their inputs. @Victor Manuel Romero Rodriguez <victor.rom...@fintecheando.mx> @Jose Hernandez <jose.hernan...@fintecheando.mx> Based on the performance testing you have done on Fineract-CN to date, can you give some feedback to Jasper and his team?
