Hay @coinlend,

Thank your for your question :) Actually I think you already went for the solution with the best performance 👍

Depending on what you are exactly doing it could boost the performance a lot if you go for a datacollector/datapresenter architecture. The datacollector would periodically insert the comment operations in a db so on a request the presenter only needs to perform a sql query instead of pulling all operations from a steem node for every single request .

Hope that helps at least a bit 💪
