sleep profiler

It can be faster than restarting after shutting down! And all the work before sleep can be inherited without requiring a reboot. If you do not use the computer for a long time, it is best to choose shutdown. Hibernation is a power-saving state designed primarily for portable computers, in this state, the open documents and programs are saved to a file on the hard disk (which can be understood as a mirrored memory state), which reads the data fro

Implement sleep with the timer control and sleep with the timer control Sometimes we need code execution delay, which requires the Thread. Sleep () method, but this method will cause the interface to be suspended when the main Thread is used. Using the timer control not only achieves code execution delay, but also does not cause any problems. Assume that we nee

From the big aspect, the bug is nothing more than: database bug; program bug.SQL capture is useful in practical applications. For those unknown bugs, when you don't know where to go, capture SQL directly and execute SQL.Application Details 1The company does web-side projects and mobile-phone projects to integrate data.

Original: 16th--handling locks, blocks and deadlocks (3)--Detecting deadlocks using SQL Server ProfilerObjective:As a DBA, it may be common for colleagues or customers to respond to frequent deadlocks that affect the use of the system. At this point, you need to detect and deal with such problems as quickly as possible.Deadlocks are caused when two or more of the transactions are blocked from one another. In this case, two transactions will wait indefinitely for the other to release the resource

Label:Preparatory work:In order to detect deadlocks, we need to simulate the deadlock first. This example creates two transactions using two different sessions. Steps:1. Open SQL Server Profiler 2. Select "New trace" to connect to the instance. 3. Then select "Blank" Template: 4. On the Event Selection page, expand the Locks event and select the following event: 1. Deadlock graph 2, Lock:deadlock 3, Lock:deadlock Chain 5. Then open the TSQL event

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
