I'm doing performance testing for one application which works on AIX.
But I don't know which performance parameters of memory need to be collected. Now, I just know very few:

They are all collected by "vmstat" command.
I want to know, except for above... (2 Replies)

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... (4 Replies)

3. IP Networking
Hello all!
I have the need to performance-test a MPLS switch, I was thinking of using iperf to accomplish the task.
I had in mind using a linux box with a Gigabit interface connected to a L2 switch on a 802.1Q trunk. In the interface I would create 20 VLANs with 20 different IP subnets.

dbd::gofer::transport::null
DBD::Gofer::Transport::null(3) User Contributed Perl Documentation DBD::Gofer::Transport::null(3)
NAME
DBD::Gofer::Transport::null - DBD::Gofer client transport for testing
SYNOPSIS
my $original_dsn = "..."
DBI->connect("dbi:Gofer:transport=null;dsn=$original_dsn",...)
or, enable by setting the DBI_AUTOPROXY environment variable:
export DBI_AUTOPROXY="dbi:Gofer:transport=null"
DESCRIPTION
Connect via DBD::Gofer but execute the requests within the same process.
This is a quick and simple way to test applications for compatibility with the (few) restrictions that DBD::Gofer imposes.
It also provides a simple, portable way for the DBI test suite to be used to test DBD::Gofer on all platforms with no setup.
Also, by measuring the difference in performance between normal connections and connections via "dbi:Gofer:transport=null" the basic cost
of using DBD::Gofer can be measured. Furthermore, the additional cost of more advanced transports can be isolated by comparing their
performance with the null transport.
The "t/85gofer.t" script in the DBI distribution includes a comparative benchmark.
