browser and proxy caching Tip 22: Use Server.Transfer instead of Response.Redirect whenever possible Tip 23: Add a slash at the end of the directory URL Tip 24: Avoid using server variables -------------------------------------------------------------------------------- Brief introduction Performance is an attribute. You need to design your performance in advance, or rewrite your application later.

rules to add to the engine. Some of these rules are: Avoid excessive local variables Avoid using private code that is not invoked Avoid an internal class that is not instantiated Avoid the use of unsealed features Avoid unnecessary casts Initialize a static field of a reference type inline To mark an assembly with NeutralResourcesLanguageAttribute Mark members as Static and so on. 24.asp.net Performance Monitoring Too

aspects of Java application performance are stability and reliability. Under SLA umbrella with 99.9% typical available targets, stability and reliability are particularly important for program operations. These systems should have a high level of fault tolerance and a rigorous budget for applications and resources to prevent the multi-meter effect. This approach prevents some of these situations, such as the use of all available physical, middleware,

Because of this simplicity, many developers will not spend time designing their application structures for better performance. In this article, I'll describe 10 tips for writing high-performance WEB applicatio

Code checking and optimization via FxCopFxCop is a code analysis tool that uses a rule-based engine to check out the non-canonical parts of your code, and you can customize your own rules to add to this engine. Some of these rules are: Avoid excessive local variables Avoid using private code that is not called Avoid internal classes that are not instantiated Avoid the use of unsealed features Avoid unnecessary casts Initialize a stati

Like all relational databases, MySQL seems to be an elusive monster. It will stop at any time, limit the application to stagnation, or put your business at risk.In fact, many of the most common errors are hidden behind MySQL performance issues. In order to ensure that your MySQL server is always running at full speed, it is important to provide consistent performance and eliminate these errors. However, the

difference.On devices that do not have a JIT, reading the cache domain is about 20% faster than reading the actual data directly. When there is a JIT, the domain reads and the local reads basically no difference. So optimization is not worth it unless you think it makes your code easier to read (which is also true for final, static, static final fields).Method 11: Get the benchmark for performance tuningBefore you optimize, you should make sure that

jsperf to test a method of speed, do not be in the dead, local conditions, to avoid falling into the small optimization and pay too much energy.About rendering you can use some skeleton diagrams to improve the user experience.Some ideas As for the performance experience, you can actually imagine building a house, which would be more time-consuming if it was the entire refurbishment, but would improve per
