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

Monitoring and Analyzing database operations-there are many articles on p6spy, SQL profiler, and irontrack SQL. I have done this by referring to http://www.ibm.com/?works/cn/java/j-lo-p6spy, We use p6spy and irontrack SQL for monitoring. The online write implementation process is Download the p6spy package or its source package;Put the jar package p6spy. jar of p6spy into classpath, if it is a Web application, put it under yourwebapp/WEB-INF/lib/direc

I often look at the SQL Profiler trace and feel that it is not convenient to store it as a file. After storing it in a database table, you can simply query it. However, the eventclassid column in the saved table displays numbers, unlike the ones used in profiler.ProgramShown RPC: StartingSP: StartingSP: stmtstarting And so on. After searching online, I found the following script to display eventclassid as the name. SelectTe.Name,T.*From

Label:The role of replay tracking You can use a trace as a test tool, and when you call some stored procedures in the correct order, you will be able to regenerate specific failures. Tracking templates There are four options for saving a trace (file-to-Save As) 1. The trace files option is used to save the data in a binary format file, which is the fastest, and the least disk-byte-consuming method. 2. The trace table option is used to save the data to a new or pre-created table in the user-sele

Before use, you need to confirm the framework version, if it is 4.0 then use the following assembly to In the project that created Isessionfactory, reference the Nhprofiler installation directory under the HibernatingRhinos.Profiler.Appender.v4.dll2. Before creating the Isessionfactory statement (new Configuration ()). Configure ().

It tells you what event is being monitored for each row. When you save this trace to a table you can see That the eventclass no longer has a description but an ID. So how do you map this to a description? If you know where

SQL profiler is a good thing. This greatly facilitates viewing the execution of SQL statements and helps us understand many internal SQL states. So there is no other way to implement it except to run SQL profiler? Of course not. Here is a simple example: 1. Use the system stored procedure sp_trace_create to create a trace. This SP can be found on-line help. Declare @ traceidout int, @ on bit, @ RC int-- Def
