database connection declaration and result set is not closed, code redundancy and other failure codes.The second step is to detect a Java memory leak. Here we usually use some tools to check the memory leak of Java programs. There are several professional tools on the market to check the Java memory leaks, they basically work the same principle, all through the monitoring of the Java program runtime, all object application, release and other actions, the memory management of all the information

Built-in profiler implementation is very simple, in ruby2.2 only 150 lines of code, you can see its implementation profile.rb. The built-in profiler is very convenient to use, just add-rprofile parameters. For example: Perform: Ruby-rprofile test.rb The output results are: By printing out the results can be very obvious to see the time-consuming method. The built-in

Administrator | data | The adjustment and optimization of database database may be one of the most important and critical tasks for a database administrator. Unfortunately, tuning and performance tuning for databases like SQL Server is not an easy task. SQL Server has several monitoring and debugging tools that are powerful but difficult to master. Fig. 1 Coefficient similar profiler Now, however, there is a coefficient. It is a new product release

Label:The use of MySQL ProfilingIn the first section of this chapter we also mentioned the performance bottleneck of using the query Profiler to locate a query, and here we describe in detail the purpose of Profiling and how to use it. To optimize a query, we need to know exactly where this query's performance bottleneck is, is it consuming too much CPU, or does it require too many IO operations? To be able to understand this information clearly, in M

In the previous article, we described the Perfmoncollector elements related to performance counters in the configuration file, which we will cover the PROFILERCOLLECTOR elements related to tracking data.In the previous article using the Sd_detailed.xml configuration file in my local collection of 5 minutes trace data file 7Mb, then did not do anything else, imagine if in a busy production environment, the resulting trace file size will be larger.The tracking data is related to the added tracking

the likelihood of deadlocks by analyzing the detected deadlocks. There are two ways to look at deadlocks, one is through the trace on the server side, and the other through SQL Profiler, first let's look at the trace to catch a deadlock. 　　Look at the deadlock through trace. When a deadlock occurs, the deadlock information can be uploaded to the log via the server trace. In the era of SQL Server 2000, only trace flag 1204来 can be turned on, because t

Unity for some time, has been heard unity can be on the Android real Machine debugging, Miss a long, finally successfully debugged.The information on the web is rarely felt and is hereby recorded for sharing.The process is as follows:1. To hit the Android version of the package, it is important to check the debug three options tick, respectively, development build, Antoconnect Profiler (Connection Profiler)

I am very grateful to you for your feedback and support, especially for the injection of some bricks. Thank you for your criticism and have benefited a lot. My first job was the development of WPF. Till now I like this technology very much. from ignorance to the present, I have some WPF development qualifications, which is a rough process. My friend saw that I wrote the full introduction to VS2013, and he recommended me to write a WPF article. I thought about it, it is true that many of my frien

, one is disk file Io, one is the driver Io (such as: Network card), one is the memory paging rate. These three things can affect the performance of the system.3) Then, look at the network bandwidth usage, under Linux, you can use the Iftop,iptraf,ntop,tcpdump these commands to view. Or use Wireshark to see.4) If the CPU is not high, Io is not high, memory usage is not high, network bandwidth usage is not high. But the performance of the system does not go. This indicates a problem with your pro
