The bean configured in spring is the default Singleton, so in the program, the speed of getting an instance must be faster than creating an instance, saving resources. During the actual test today, we found that a new object is much faster than a spring object. Next I added

Adding notnull fields to Oracle11g is faster than 10g-New Features
Adding a not null field before 11g is very slow, and it is very fast after 11g. We will first perform a test and then explore the principle.

-----------------------------
clock speed was greatly reflected, it has been flushed to 3.4 GB, the CPU of a long pipeline can only make full use of its advantages at a high frequency. It uses a very high frequency and a short clock cycle to make up for the time wasted in re-executing the command when the pre-read command fails..
However, the theoretical frequency limit of the Pentium 4 processor with a 20-level pipeline and a 0.13 micron Northwood core is 3.5 GB. What should I d

Permissions validation, data validation, exception handling, transaction processing, data transformation, and so on are all done on the infrastructure, and the module developer does not need to write the code.The application service method automatically applies the Unitofwork (unit of work) mode, except for methods that start with get, and other methods to automatically open database transactions.
Re-post some of the front-end interface
, over time, the total user memory over 2G, the program will be directly collapsed. At this point you will certainly ask, how should I solve this problem? Since we can't count how much user memory is being used, how much more can we get new? Fortunately, Microsoft has provided us with a good allocation heap method, which is to allocate the heap with HeapAlloc. Yo

Why Facebook's hiphop to convert PHP to C + + instead of converting PHP into a compiled language ... Is it faster to execute the compiled file directly?
Reply content:The first thing to do is to look at the whole history: Facebook has launched the HHVM (HipHop VM) after HipHop (HPHPC), which compiles PHP into C + + and then compiles it to machine code (at runtime

There are about three ways to get the millisecond value nowJava code
Method One

Method Two

Last month, Joe Stagner posted a seriesArticleCompared the execution performance of PHP and ASP. NET, resulting inProgramA large number of responses from members. Joe said he would continue this test and look for a more appropriate way to draw conclusions that are as valuable as possible for the actual project.
JOE:
In general, the purpose of performance testing is to try to prove that one party is
not a header file but some form of compilation module, multiple source files (compilation unit) reference the same module then the compiler only needs to parse the module generation AST reuse, the compilation speed can also improve a lot.C/C + + stupid text insertion form of the #include, the assembly compiler completely eliminates the compilation of header files, you refer to the direct supply of the type and method of God horse metadata, the compiler directly to use the good.Finally, because
