Apache JMeter
						
									 is a 100% pure Java desktop application designed
	  to load test functional behavior and measure performance.  It was
	  originally designed for testing Web Applications but has
	  since expanded to other test functions.
	
						
							  									 				
								What can I do with it?
						
							  									 				
								
	  Apache JMeter may be used to test performance both on static and dynamic
	  resources (files, Servlets, Perl scripts, Java Objects, Data Bases and
	  Queries, FTP Servers and more). It can be used to simulate a heavy
load on a server, network or object to test its strength or to analyze
overall performance under different load types. You can use it to make a
graphical analysis of performance or to test your server/script/object
behavior under heavy concurrent load.
						
							  									 				
												
								Using JMeter
						
							
							  									 				
								What does it do?
						
							  									 				
								Apache JMeter features include:
						
							  									 				
								
	
												- 
								Can load and performance test HTTP and FTP servers as well as
		arbitrary database queries (via JDBC)
						
- 
								Complete portability and 
												
								100% Java purity
						
									.
						
- 
								Full 
												
								Swing
						
									 and lightweight component support (precompiled JAR uses packages
		
												
								javax.swing.*
						).
- 
								Full 
												
								multithreading
						
									 framework allows concurrent sampling by many threads and
		simultaneous sampling of different functions by seperate thread groups.
						
- 
								Careful 
												
								GUI
						
									 design allows faster operation and more precise timings.
						
- 
								Caching and offline analysis/replaying of test results.
						
- 
								 Highly Extensible:
	  
												
								
		
												- 
								Pluggable Samplers allow unlimited testing capabilities.
						
- 
								Several load statistics may be choosen with 
												
								pluggable timers
						
									.
						
- 
								Data analysis and 
												
								visualization plugins
						
									 allow great extendibility
		as well as personalization.
