I found the results somewhat strange. When you say Code I assume you mean Microsoft VSCode? If so, I am using it as my main IDE since it has replaced sublime and I am regularly opening 60Mb+ sql files. It rarely needs over 8s to do so. Memory consumption always depends on loaded plug-ins and config though. It is big, definitely bigger than most others (exception Atom) but can’t say I’d trade it for anything else (on account of usable plugin ecosystem and the fact that it’s never taken over 1gb of ram, which given the consistent performance seems acceptable)
