Suggested tool / approach for performance testing

What is a good approach for a performance testing tool suite for web applications? I am specifically interested in tools that execute a certain set of tasks well as opposed to tuning high traffic sites. In other words, a profiler would be a good idea to have, although I understand these tools are specific to a language. A profiler will help me understand where most time is spent in executing a particular part of the code, but does not provide me with a start-to-end view of where performance could be improved. Is there a tool that provides profiling data on where in the chain browser, web server, application server, database server most time is spent?

Thanks in advance

NAME
asadmin-create-profiler, create-profiler - creates the profiler element SYNOPSIS
create-profiler --user admin_user [--password admin_password] [--host localhost] [--port 4848] [--secure|-s] [--passwordfile filename] [--terse=false] [--echo=false] [--interactive=true] [--classpath classpath] [--nativelibpath native_library_path] [--enabled=true] [--prop- erty (name=value)[:name=value]*] profiler_name Creates the profiler element. A server instance is tied to a particular profiler, by the profiler element in the Java configuration. Chang- ing a profiler requires you to restart the server. This command is supported in remote mode only. OPTIONS
--user authorized domain application server administrative username. --password password to administer the domain application server. --host machine name where the domain application server is running. --port port number of the domain application server listening for administration requests. --secure if true, uses SSL/TLS to communicate with the domain application server. --passwordfile file containing the domain application server password. --terse indicates that any output data must be very concise, typically avoiding human-friendly sentences and favoring well- formatted data for consumption by a script. Default is false. --echo setting to true will echo the command line statement on the standard output. Default is false. --interactive if set to true (default), only the required password options are prompted. --classpath Java classpath string that specifies the classes needed by the profiler. --nativelibpath automatically constructed to be a concatenation of the Application Server installation relative path for its native shared libraries, standard JRE native library path, the shell environment setting (LD_LIBRARY_PATH on UNIX) and any path that may be specified in the profile element. --enabled profiler is enabled by default. --property name/value pairs of provider specific attributes. OPERANDS
profiler_name name of the profiler. Example 1: Using create-profiler asadmin> create-profiler --user admin --passwordfile passwords.txt --host localhost --port 4848 --classpath com.iplanet.ias.profile.Profiler --nativelibpath /u/home/lib --enabled=false --property defaultuser=admin:password=adminadmin sample_profiler Created Profiler with id = sample_profiler Where: sample_profiler is the profiler created. EXIT STATUS
0 command executed successfully 1 error in executing the command asadmin-delete-profiler(1AS) J2EE 1.4 SDK March 2004 asadmin-create-profiler(1AS)
