performance profiling tools

For C ++: Memory analysis tools: 1. c ++ Memory Leak Detector-memory validator (http://www.softwareverify.com/index.html) 2. Other as references: purify from IBM Performance profiling tools: For C #: Memory analysis tools: As developers, we are often faced with addressin

.jhat: Analyze Jmap dump out of the heap to provide access in the form of Web pages. The Jhat function is basically weaker, is very memory-intensive, is largely unusable in the case of large heap files (for example, over 1G), and Eclipse Memory Anaylzer is an excellent alternative. Use the following format:jhat {DumpFile} requires additional startup parameters when the heap file is large, such as the following jhat–j-mx512m {dumpfile}Access http://localhost:7000 to see the results after analysis

C + + Performance profiling (i), profiling Analysis of C + + performance (i.) Performance problems are not just "technology" can be solved, it is often the framework, testing, assumptions and other comprehensive problems. However, for an engineer, must start from childhood,

Profiling (profiling) is a technology that focuses on measuring where server time is spent, where performance is response time.Measurement is a challenging task, and the results of the analysis are equally challenging, measuring where the time is spent, and knowing why it is different.profiling typically has two steps :The time taken to measure the task;The resul

thread profiling is mainly used to identify memory problems in multi-threaded applications. It generally includes three aspects: Status changes of a thread Deadlock Distribution of the state of a thread during its life cycle Profiling startup settings: similar to the run and debug startup settings in eclipse, you also need to perform startup settings before

In the development process of Java program, it is unavoidable to encounter memory usage, performance bottleneck and so on. javaprofiler Tools Help developers locate these issues quickly and effectively, making them an important tool in the Java development process. At present, there are many kinds of JavaProfiler tools on the market, this article will briefly int

possible with a certain workload.? CPU utilization is only a symptom, not a good measurable goal.? The increase in throughput can be seen as a byproduct of performance optimizations that allow the server to execute more queries per second. Because the query execution takes less time per second. (Throughput is the inverse of performance: number of queries per unit of time, QPS,QPM, etc.)Principle two: Unabl

-tools-common on Ubuntu, linux-base on Debian, perf- Utils on ArchLinux, or perf on Fedora. Then you can profiles the system like:$ perf record-a-G sleep # Record system for 10s# display reportThat would display this handy curses interface in basically any hardware platform, which can use to drill down to the A Rea of interest.See Brendan Gregg's perf examples for a further up to date and detailed exploration of perf ' s capabilities.Other system wid

Objective: Keep Empty cup spirit, use performance analysis, focus on measuring server time spent where, think 1, how to confirm that the server has reached the best performance state, 2, why a statement is not fast enough, the diagnosis is described as "pause, accumulate, card dead" some intermittent troubleshooting; Next, we will introduce some tools, techniqu

understanding performance issues related to ORM, and it provides a degree of understanding, otherwise 4 separate tools are required. The ANTS Performance Profiler also has stringent requirements for the speed at which results are obtained. The user tells us the most critical information when diagnosing a performance
