Wow, sizing information.
we don't have that type of information yet. We tried to stress test jboss
1.0 but run with memory exceptions that come from the pools (possibly
JOnAS's, they have the problem reported there too, ;0)
jBoss 2.0 is in development but we will need sizing information soon. Give
us a couple of weeks to get to beta (coming fast and furious) and we will
stress this thing.
I am looking at your numbers and I am not concerned AT ALL about the numbers
you present (I was running 1k update *100/second* no so long ago on jBoss
1.0, but from one client only... so that would mean 1000 clients on your
software...)
The problem is going to be the network stack and RMI scalability. I know
for a fact that RMI will not hold 1000 clients. since we thread on one
object only it might be the case that the number can go around 100 concurent
threads in our one object (haven't tested it yet).
IF YOUR STUFF RUNS IN VM!!! then it's a different ball game again the
problem is in RMI so if your clients are servlets or other applications
running in the same VM then we bypass the RMI stack altogether and use the
thread you call with.
Then you bypass the RMI problem and go down to the number of threads your
server can really handle.
In short, your query update rate is not significant at 500MHz(the old bench)
and the network can be optimized depending on your client architecture
(native apps, servlets, jsp etc etc)
