I have yet to see a web browser app that provides equal performance to a native application. When I am accessing my mac from windows, performance is definitely an issue (although I will concede that the weakest link in the chain may be elsewhere) So am I missing something? Is the only way to use parallels access on Windows really just through a web browser? I've seen the tips for increasing performance but I'm not keen on changing several mac options every time I want to use my mac remotely. Thank you.
