Steve,
This is just due diligence. We have already calculated the network-side
increased bandwidth utilization through packet captures. We saw 500-800%
increased packets using the new development over the old. Now we need to
see what effect this app has under load on the back-end, both the MF
servers and the DB servers. We are already planning to do the load
testing manually by involving 70-100 of our IT and corporate staff, but
I was hoping that there might be some automated tool to help.
Regarding enhancements on the client and/or server-side to justify
upgrades, we need the hard numbers. It's not enough to point out to
management that this is just a bad idea and painful to the users; they
need to see the hard numbers and that's the direction toward which we
are heading. When it's all said and done, we may indeed upgrade to PS4
or even Provision's PMF. But that would be in conjunction with any
available mods to the code to minimize animation and bandwidth
utilization. We are hoping that the cumulative effort may result in an
acceptable product for the end users. That still remains to be seen...
Thanks,
rob

Rob,
I realize you have heard this already and that you won't like this
response, but you should not expect a very good result using a rich
Flash application on Metaframe XP. If you do not have any load
simulator you should be able to do it by hitting one server manually
with some number of sessions and extrapolating out the results. If you
were using PS4 you would get better multi-media performance and you
would the CPU optimization which would keep each session at a max of
about 10-12% of overall CPU. I do not know how Flash affects CPU but you
may need to watch this, if it grabs 100% for each session you wont have
any native tools to prevent that.

Subject: [THIN] Flash/Flex Load Testing
Another Flash 9/Adobe Flex-related question. I know Flash in MetaFrame
is a bad idea, but changing it is not an option. What we need to do is
loadtest it and it appears that there aren't any options available to us
for automated loadtesting via user scripts, according to our outsourced
loadtesting expert. Does anyone know of any way that we might loadtest
Flash 9/Adobe Flex for a web-based application running over Citrix MF XP
1.0 FR3/SP4 on Window Server 2003? Any help would be greatly
appreciated...
Thanks,
rob
