It's probably more about how you allocate the resources than your language choice. I read that GAE was built the be language-agnostic so there is probably no builtin advantage for any language, but you can get an advantage from choosing the language you are comfortable and motivated with. I use python and what made my deployment much more cost-effective was the upgrade to python 2.7 and you can only make that upgrade if you use the correct subset of 2.6, which is good. So if you choose a language you're comfortable with, it's likely that you will gain an advantage from your ability using the language rather than the combo language + environment itself. 

In short, I'd recommend python but that's the only app engine language I tried and that's my choice even though I know Java rather well the code for a project will be much more compact using my favorite language python.

blocks|key|521059|text|我没有使用过Go，但我强烈怀疑它会更快地加载和执行实例，并且纯粹因为它是编译的，所以使用的内存更少。根据该小组的传闻，我认为Python比Java响应更快，至少在实例启动时间上是这样。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|521060|实例加载/启动时间很重要，因为当您的实例遇到超过其处理能力的请求时，它会启动另一个实例。这会使请求花费更长的时间，可能会给人一种网站通常很慢的印象。Java和Python都必须启动他们的虚拟机/解释器，所以我预计Go在这里会快一个数量级。|521061|还有另一个问题--现在Python2.7可用了，Go是单线程的唯一选择(讽刺的是，Go被设计成一种现代的多进程语言)。因此，尽管Go请求的处理速度应该更快，但实例只能串行地处理请求。不过，如果这种限制持续很长时间，我会感到非常惊讶。|521062|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

I haven't used Go, but I would strongly suspect it would load and execute instances much faster, and use less memory purely because it is compiled. Anecdotally from the group, I believe that Python is more responsive than Java, at least in instance startup time. 

Instance load/startup times are important because when your instance is hit by more requests than it can handle, it spins up another instance. This makes that request take much longer, possibly giving the impression that the site is generally slow. Both Java and Python have to startup their virtual machine/interpreter, so I would expect Go to be an order of magnitude faster here.

There is one other issue - now Python2.7 is available, Go is the only option that is single-threaded (ironically, given that Go is designed as a modern multi-process language). So although Go requests should be handled faster, an instance can only handle requests serially. I'd be very surprised if this limitation last long, though.

Will google Go use less resources than Python and Java on Appengine? Are the instance startup times for go faster than Java's and Python's startup times? 

Is the go program uploaded as binaries or source code and if it is uploaded as source code is it then compiled once or at each instance startup?

In other words: Will I benefit from using Go in app engine from a cost perspective? (only taking to account the cost of the appengine resources not development time)

google Go会比Appengine上的Python和Java使用更少的资源吗？go的实例启动时间比Java和Python的启动时间快吗？go程序是作为二进制文件还是源代码上传的，如果它是作为源代码上传的，那么它是一次编译还是在每次实例启动时编译？换句话说:从成本的角度来看，我会从在应用程序引擎中使用Go获益吗？(...
