increase the number of valid data accesses. This is more difficult than I-Cache Optimization. The following is a list of code optimization tips that need to be constantly supplemented, optimized, and filtered. 1) code adjacency (put the relevant code together), recommendation index: 5 stars Put the relevant code together has two meanings: first, the relevant source files should be put together; second, the related functions should also be adjacent in

function-oriented table. This colleague is also a good practice because she tells you how to distinguish the nature of the method, and calling this method does not change the state of the object.28. The use of intrinsic get,set methods should be avoided wherever possible.In Android programming, the invocation of a virtual method has a lot of cost, more than the cost of an instance property query. We should use the Get,set method when we outsource the call, but it should be called directly when

problem.27. Consider using static methods,If you don't have to go to the outside of the object, make your method a static method. She will be called faster because she does not need a virtual function-oriented table. This colleague is also a good practice because she tells you how to distinguish the nature of the method, and calling this method does not change the state of the object.28. The use of intrinsic get,set methods should be avoided wherever possible.In Android programming, the invocat

28 Tips for improving ASP performance and appearance Len Cardinal, Senior Advisor, Microsoft Consulting Services George v. Reilly Microsoft IIS performance lead adapted from Nan Cy Cluts's Article Developer technical Engineer Microsoft Corporation April 2000 Summary: This article describes the techniques for optimizing ASP applications and VBScript. Introduction

AvaScript is now the most popular language. It can do many things-website interfaces, server terminals, games, operating systems, robots, and many more. But to be honest, even if JavaScript is so crazy, it is already the most popular language. It can do a lot of things-website interfaces, servers, games, operating systems, robots, and so on. But to be honest, even if it is so crazy, its performance has not reached its limit. Yes, it is improving, but

used to control the process.4. Use local variables as much as possibleLocal variables, the parameters passed when the method is called, and the creation of temporary variables are saved in the stack (stack), faster, other variables into static variables, global variables are created in the heap (heap), slower.Extension: The stack is allocated by the system, faster, the stack uses a first-level cache, they are usually transferred to the storage space, the call is immediately released, the heap i

the data processing to the SSAS Cube Dimension (also disk files), again generate unequal disk overhead, in addition to distinct to recalculate, the former need to the membership dimension of this large table to do tier to heavy, the latter only need to the membership level this small dictionary table to do the heavy, obviously the calculation is different weight class, These are just the cost of the process, perhaps you are doing in the night, not care these, then the

Closure (closure) is also a very common coding pattern, because it implicitly carries context variables, so that the algorithm code can be more concise.But behind any "convenience" and "elegance" is often a more complex implementation mechanism, which is nothing more than a syntax sugar or compiler that hides the details. Ultimately, these will become additional costs at run time by CPU, runtime burden. Even for unreasonable use, causing performance p

JavaScript is now the most popular language, it can do a lot of things-web interface, server side, games, operating systems, robots and so many many. However, to be honest, even if it is so wildly popular, its performance has not reached its limit.Yes, it's improving, but until it catches up with local apps in every way, you have to use some tricks to optimize its performance when doing a hybird hybrid appl

Nbsp; most of the Linux server releases offer better performance than the proprietary system. However, this does not mean you can rest assured that you do not need to optimize the server performance. In fact, there are always some ways to improve performance, regardless of the operating system. Nbsp; This article lists five Linux server releases that improve the

As a built-in type, channels (channel) get a lot of support from the runtime, and its own design is ingenious. But anyway, it's essentially a queue, and locks are unavoidable when multiple goroutine operate concurrently. At some point, this competitive mechanism can lead to performance problems.Here is an example of simply using the channel to send and receive data, for "accurate" measurement of the transmit and receive operation

Tips: How to improve MySQL Performance (1 ). I. question raised: at the early stage of application system development, due to the small amount of data in the development database, the performance of various SQL statement writing methods cannot be realized for Querying SQL statements and compiling complex views.

program runs on, so If your machine has a discrete graphics card, running a WPF program will be smoother. In addition to improving the hardware configuration, let's take a look at 10 soft methods to improve the performance of WPF programs. 1, reduce bitmapscalingmode, accelerate image rendering when you include animations in your WPF program, you can use the Bitmapscalingmode property of the Renderoptions object to reduce resource consumption, The

they can be loaded as efficiently as possible. This is especially important when we talk about graphical resources. If you add a large image resource that you can take advantage of, you will not be able to use other application resources efficiently by loading and resizing.8: Using the Hierarchy Viewer toolThe Hierarchy Viewer tool can help you debug your application layout. It also provides valuable analysis information to understand how much time it takes to measure, render, and draw each vie

results after repeated compilation, why not skip the compilation process completely?With the PHP accelerator, you can achieve this completely. it caches the machine code compiled by the PHP script and allows the code to be executed immediately as required without tedious compilation.For PHP developers, there are currently two available Cache solutions: APC (Alternative PHP Cache, optional PHP Cache ), it is an open-source accelerator that can be installed through PEAR. Another popular solution

Here, with MSDN tips, I'll do some finishing work. All applications should be compliant. Here's a list

, which can significantly improve performance. Experience shows that the biggest improvement in SQL Server performance is due to logical database design, index design, and query design. Conversely, the biggest performance problems are often caused by deficiencies in these same areas. In fact, the essence of SQL optimization is that the result is correct, with th
