iis 7 - WCF Performance Slow for the first call -

-

I have a WCF service installed on IIS7. I noticed that the first call for my service is always very slow. Fast & amp; Acceptable

If for some time no call is made in service, then it goes back to sleep mode. Then the next call takes a long time again.

Any remedy for this problem?

is due to process management on IIS when there is no call for some time IIS releases release And stops the process. This is the reason why you can see that it is slow for the first request and the request after a long delay. Because for the first time or after long silence, the IIS loads everything from scratch. GIT compliant runs and so on ...

Also note: When you are hosting WCF services on IIS, WCF services enjoy all the features of ASP.NET applications. You should be aware of these features because they can create unpredictable behavior in the world of services. One of the key features is application recycling, including application recycling and recycling process. Through the IIS management console, you can configure different rules when you want to recycling. You can set some thresholds on time and on the amount of processed requests. When IIS recurs a worker process, all application domains will be reused within the worker process

If you need Automatic start : Windows Service Control Manager Startup type to automate you, so that once the Windows starts, the service will start without an interactive logon on the machine. So you can use the Windows service as a host.

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
