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

So, I've been told and heard a million times that malloc and free are expensive calls to be avoided. So many times I avoid malloc by reusing already allocated memory blocks. Store them on free lists somewhere myself and don't call free when I know malloc will be called very shortly thereafter.

asadmin-create-profiler(1AS) User Commands asadmin-create-profiler(1AS)
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.
