SUMMARY: Performance benchmarking tools

Greetings All,

     Well, it's been 48 hours since I posted this so I'll go ahead with=
 my
summary.  I've got to admit that I'm a little disappointed that I only
received 2 responses to this post, and one of those was correcting my
spelling (first typo I've ever made in my life ;-)!  Anyway, thanks to =
Don
Hoover and Noel Hunt for taking the time to reply.  I've included my po=
st
and their replies at the end of this e-mail.  I'm still interested in
performance tool web sites, if anyone knows of some good ones...

     BTW, here's 2 good sites that I'm already aware of:  1) Sun's resi=
dent
performance guru, Adrian Cockcroft, maintains a page at
www.sun.com/sun-on-net/performance.  2) There's also an excellent (exce=
pt
it doesn't have much info on gigabit ethernet) page on TCP tuning at
www.sean.de/Solaris/tune.html maintained by Jens-S. Vockler.

     Thanks again, everyone...

Subject:  Performance benchmarking tools



Greetings Again All,

     I just posted a summary to my gigabit ethernet performance problem=
s.
The bottom line was that I wasn't using the right tool for the job, des=
pite
the fact that I had used three different tools to attempt to test the
performance of our gigabit ethernet network.

     Now, as anyone who's done any performance benchmarking knows, you
should never use just one tool when doing performance benchmarking.  Th=
e
vendors know this; that's why they try several different benchmarks and=

then use the one that gives the best results in their advertisements!  =
;-)

     This whole experience with benchmarking gigabit ethernet has left =
me
with a nagging question:  how does one ensure that they're using the
appropriate tool(s) for the job?  rcp and ftp had proved fine for testi=
ng
fast ethernet.  Consequently, I wasn't even aware of ttcp.  Does anyone=

have any recommendations on any web sites, magazine articles, books, et=
c.
concerning performance benchmarking tools?  I'd prefer web sites,
especially if they provide the ability to download the various tools.

     Thanks once again.  I think that the number of people who responde=
d to
my previous post shows yet again what a valuable resource this list is.=
  Of
course, I'll summarize...

Here is the perfect  tool... its the ultimate network benchmarking tool=
..
we use it for all kinds of  stuff, and its cross platform.
