![]() ![]() API functions are known in advance, well-tested, often used, and not subject to change, so there’s a priori no benefit in not compiling them in advance, and doing that is likely to reduce performance. Freezes briefly (from less than a second to a few seconds) from time to time, for no obvious reason.įor the rest, they behave very much like native apps.ĭo you mean that when you download the runtime, you don’t get a pre-compiled copy of the API (or at least of its most frequently used functions) ? This seems strange. Resizing a window is much more choppy than with a native app, I don’t know exactly why. Very long startup times (given your explanations, I suppose it’s because many methods are executed for the first time and thus compiled) Net apps much less often), I can separate applications using it from native code through the following : In my experience of managed code (mostly Java and Python, though, I encounter. Equally bad code can be written in any environment, the problems caused by bad code will just slightly differ. Net so I can’t really see the advantage of only using API functions.Īpplications in a managed environment can be slow when written badly, but if you think that only “expert” programmers use unmanaged environments, you are just being very naive. Net, what might be a single instruction in F# can be the equivalent of a whole list of instructions in C#.Īnd use API functions as much as possible. Can you define what you mean by “little instructions”? Again in. This also doesn’t make any sense at all in managed environments. You must try to use as little instructions as possible in your code, … Net application? In most applications you won’t even notice when a garbage collect occurs. This happens the first time a method is called (so there might be a performance penalty when a method is called for the first time), but this needs to be done only once.Īnd the various tricks like GC that occur under the hood to make the programmer’s life easier Net (a similar environment is used on Windows Phone 7) the managed code is actually compiled to native code, but this only happens at runtime. I am not trying to deny that applications on Windows Phone 7 are slow (I have not yet used a phone running this OS) and I am also not trying to say that managed applications run as fast a unmanaged applications, but I think you have a lot of misconceptions about managed environments.Įach instruction of managed code is much more costly than an instruction in machine code ![]()
