I am about to commit an MBean / EJB pair whose only purpose in life is to
stress the cache locking logic.
Because it is an MBean it never goes through the RMI layers and so we are
seeing RAW performance of the logic that does the thread mutex semaphore and
all taht... that was the part I had to optimize when I went to SUN... now
with the new logic 50 threads all pinging on 1 object.
on my new athlon it crawls to an halt at 50 clients in parallel (they wait
100ms before pinging again) and there is almost no invocation going
through...
:(
anybody ELSE seen this? I am almost leaning towards TOTALLY removing the
passivating caches and associated mutex logic as is
Ok I will say the word... this is shite ...
or is it just me?
