NHibernate Profiler is a tool that can monitor SQL statements in NHibernate1. Download NHibernate Profiler2. Add a reference to your NHibernate project (below the NHibernate Profiler root directory)HibernatingRhinos.Profiler.Appender.dll3. Configure your application configuration file, my is Web service, ie. config filelog4net> Appendername= "Nhprofappender"type= "HibernatingRhinos.Profiler.Appender.NHibern

P6spy combined with SQL profiler Configuration P6spy is a dynamic monitoring framework for database access. It has been very mature for a long time. p6spy simulates a standard JDBC driver and acts as a proxy for the real underlying JDBC driver. That is to say, we only need to configure the JDBC driver used in the system as the p6spy driver, and configure the realdriver in the p6spy configuration as the actual JDBC driver, so that we can use its p

SQL Server Profiler is a performance monitoring tool for MS SQL. You can use this tool to find the SQL statements to be optimized, and then use the database engine optimization advisor tool to help optimize the database.

In use. NET to start and develop the application quickly, the next problem may be the performance tuning aspects of the program, and performance tuning can sometimes involve all aspects of the problem, such as the program host system, database, network environment, and so on, and when the program is unusually large and complex, performance tuning will become even more impossible. This series of articles will mainly introduce some. NET performance tuning tools, Web performance optimization rules

Tags: MongoDB optimizerIn the MySQL database, the slow query log is often used as the basis for database optimization, and MongoDB still has similar functions. MongoDB's own profiler allows easy recording of all time-consuming operations for ease of tuning;First, start the profiler functionThere are two ways to turn on the Profier function:The first is to set it directly in the startup parameters, and add t

Original: Using SQL Profiler to handle expensive queriesWhen the performance of SQL Server becomes worse, the following two things are most likely to occur: First, some queries produce a lot of pressure on system resources. These queries affect the performance of the entire system because the server is not able to serve other SQL queries quickly enough. Additionally, expensive queries block other queries that request the same database res

Because sometimes OS X system sleep will automatically wake up, and then sleep, every other will automatically wake up, and constantly cut off the hardware power, and then plug in power, equal to a night to restart more than 100 times, Mac life can imagineSo we have the following research, parameter testing, recommended settingsApple's default settings are as follows:Turn off the monitor, hard drive after 1

What is the difference between the sleep () method of the thread class and the Wait () method of the object that allows the thread to pause execution?The Sleep () method (Hibernate) is a static method of the thread class (threads), which causes the current thread to pause execution for a specified time, giving the execution opportunity (CPU) to another thread, but the lock on the object remains , so that it

Orm profile calls every trace session snapshot. In the SQL document, this word is translated as a snapshot and can be understood as a trace session. It can be saved on the hard disk for further analysis. For the win froms progr

Recently, for Linux development on arm, C Programs Written in windows need to be transplanted to Linux. The underlying SPI driver implementation and socket communication on the upper layer need to be rewritten, the application also needs to be changed. It does not take much effort to make the program run smoothly throughout the process. Thanks to the powerful eclipse + arm-Linux-GCC combination, however, many interesting problems are found during debugging. One of them is about the differences b

play the engine.Web-inspector inside the Cpu-profilor module can be very good evaluation of a JS function more than 10 years of the total project ratio, so you can stare at the top of the function to optimize. However, the native Web-inspector only gives the JS function's execution occupancy ratio, and does not list whether the function has been optimized, and if not, what the reason is.After reading the JS engine V8 code, we present these very critical/useful information to the code farmer thr

Some time ago, I had a performance problem with my website, and sometimes the page was very slow to open. It would take more than 10 seconds. I tried a lot of methods, including cache, disable viewstate, and Disable debug mode. The improvements were not obvious. Later, I ran into SQL Server Profiler to check the cause: a slow query dragged down the entire page. Later, the query was optimized, but not many improvements were made. Finally, an index i

SQL Server Profiler provides a blocked Process report event, which records blocking tasks that exceed the specified time. With this event, we can record the blocking information of the database. Next let's take a look at how to use blocked processreport: To use blocked Process report, you must configure the threshold and report generation frequency. Use the sp_configure command to configure the blocked process threshold option (in seconds ). By defa
