performance.If the database is using SQL Server, the work will be simpler, and we can use SQL Server Profiler directly using the default settings (but SQL Server itself is very complex, even this simple profiler tool, In the deep use of the time also have a lot of knowledge, and later I will have the opportunity to start a project on SQL Server.With an Oracle database, you can use the performance view to f

SQL Server Profiler (Profiler) helps database administrators track specific events that are performed by SQL Server databases, monitors the behavior of the database, and saves these valuable information to a file or table for later analysis to resolve problems with the database. Optimizes the performance of the database engine. This step-by-step article describes how to use SQL Server

The Oracle stored procedure needs to be written recently, as required by the company. I am a novice, after the completion of the writing of the stored procedure, it is necessary to analyze the execution time of each statement in the stored procedure in order toOptimize the entire stored procedure.Due to the use of Plsql Developer client tools, and most of the internet is introduced by the manual method of applying the profiler, using relatively chores

A. Waitfortargetfps:Vsync (vertical sync) function, which displays the CPU wait time of the current frameB. Overhead:Profiler overall time-the total record time for all items. Used to record unclear time consumption to help further refine profiler statistics.C. Physics.simulate:CPU elapsed time of the physical simulation of the current frame.D. Camera.render:CPU consumption of the camera rendering readinessE. Rendertexture.setactive:Sets the rendertex

Problem description The Unity project often chooses to use Lua as a more logical script in practice. This is because Unity itself is less friendly to heat, more flexible with Lua heat, and simpler to share code and data with the server. At present, many different Unity + Lua integration programs, the practice of using a lot of Pang classmate's Slua program. Teams that use Lua tend to be "heavier" integrations, exposing a sizable engine interface to Lua, so logically enough freedom to have full

large problem is divided into multiple thread block processing, each block of the number of threads is not too small, like this article only 1 threads, which is a huge waste of hardware resources. An ideal solution is to divide n thread blocks, each with 512 threads, to decompose the problem, often more efficiently than a single thread parallel processing or a single piece of parallel processing. This is also the essence of CUDA programming. The above analysis of the performance of the method

Usually debug SQL, using Profiler used to, but now with a machine does not have Profiler installed, and tried to install again, add new features, but no profiler options, recently debugging really can not bear to see the code logic debugging, so the internet search, found a solution, put here, As an alternative:In the case of a SQL Server installation package, us

In fact, after the discovery is still relatively simple, but there are a few more attention to the placeI. Using Unity for Android development, it is important to remember to back up the Android development environment, which is the SDK. As soon as the SDK is updated, it is possible to change the file structure within the SDK, so unity cannot find the file correctly, and the build will continue to error. Although there are various solutions online, but I personally think the first is trouble, th

What is the recommended way to loading.readobject the high cost? Loading.readobject is a resource-loading function for the unity engine that typically occurs when switching scenes and loading API calls, including textures, meshes, Material, Shader, Animationclip, and so on. If you find that the value is too high, it is recommended to vigorously optimize the associated resources for loading. For each type of resource loading, we are summarizing and sharing it in a thematic way, so we recomm
