MySQL has a built-in analyzer Profiler. With Profiler, developers can easily and quickly understand the approximate performance of MySQL
The main purpose of MySQL's SQL Performance Analyzer is to show how resources are used throughout the process of SQL execution. The parser can better demonstrate the performance problems of poor SQL.Here are some examples of how MySQL SQL Profiler is used: First, turn on MySQL SQL Profiler
SQL Server has an SQL profiler that can track the SQL statements executed by the server in real time, which is useful in many times for debugging errors. For example, the complexity of othersCode, Production system, no debugging environment, no original code ...... After checking the information, My SQL can use the following method to track SQL statements. The following method is similar to that of Linux on the Windows platform: 1. Configure the m

IOS Performance Tuning series: Use Time Profiler to discover performance bottlenecks and tune profiler Hardware wide: The fifth article in the IOS Performance Tuning series, which is expected to be updated continuously over 20 articles. The last four articles focus on memory and Analyze memory leakage, zombie objects, and memory allocation. This article introduces the use of Time
First, prefaceIn recent times, there have been two problems with websites:1. Memory usage increases slightly until the server memory fills up.2. When you visit a page, the page responds too slowly and the CPU stays high.An initial estimate of memory growth may be due to the fact that there are unsaved resources that are taking up memory, and that the CPU is high probably because of the time-consuming operations performed.Here we use the Ants Performance Prof

Using PL/SQL profiler to locate PL/SQL bottleneck code for SQL optimization, you can use SQL tuning advisor to achieve automatic SQL optimization and adjustment. For PL/SQL code, there are both SQL code and PL/SQL code. It is far from enough to use only 10046 events, because the SQL time may be very short, the entire package or process is executed for a long time, and other packages, processes, and functions are nested in the package or process. It se
There is a kind of speed called Turtle line, there is a kind of feeling called unbearable, there is a kind of desire called performance improvement, there is a kind of difficulty called the bottleneck. Everyone wants their programs to run quickly, but how hard it is to improve performance is, even getting started. Which of the following is the key to performance improvement? Which segment is the bottleneck of the program running? Do you have to add a period of output before and after each funct
each plan depends on the statistical results collected by the system, but these data are not necessarily the latest. Because you may know more about the database and data content than query optimizer, you can decide a better plan than query optimizer. Using the information provided by query analyzer, you can determine whether the plan provided by query optimizer to the declarative plan is efficient. If you are sure it is not good enough, try modifying the T-SQL statement or using the SQL prompt
