Summary of performance optimization (i): Preface

Recently in the GIX4 project has done some performance optimization, in order to facilitate with colleagues to share the experience, today is ready to put some of the relevant tips are written. These techniques are not difficult, not to say how well designed, but I think they are important. I remember when I was working on the last web system, I also supported OO's business-rich model, where I used linqtosql to achieve data access in most of the scenarios where performance was not required. In scenarios where performance requirements are high, manual SQL is used for data access. But in both ways, the same approach is used when optimizing data access. Today, the same method is used again in the GIX4.

As you can see, in applications that are programming for domain-oriented models, such optimization scenarios may be used frequently. The following two major programmes are to be written today:

1. SQL loads the aggregate object.

2. Pre-loading data.

Casually wrote the following outline in Notepad, about two times written, as follows:

     Why? Senarios.
         Shortcoming of lazy load

     Parallel Server for CSLA

     Questions remain
