Hello, I am creating an API that will connect to Bitcoin Core running on a server. The API would manage multiple wallets for a lot of users (up to 1000s)... Now I'm wondering how could I implement this to work as fast as possible. Is it possible to for example "getbalance" ("http://USER:PASS@localhost:8332/wallet/WALLETNAME") of a specific wallet without having it loaded? Because each loaded wallet takes about 10MB in memory.. And having 1000s of them loaded at the same time would take up a lot of ram and I am not sure how much stress it causes on the CPU for example, if anyone has any knowledge about this. Would it make sense for each API call to first load the wallet, execute the command and then unload the wallet? That would probably affect the performance. Any help is appreciated.
