IO

Hi Folks,
 
Does anyone know the structure of the IO stacks on blackdown on Java
HotSpot(TM) 64-Bit Server VM (build Blackdown-1.4.2-01, mixed mode)
running on Redhat ES4 (AMD_64)?
 
I'm testing a high throughput application and occasionally the
transaction journal seems to get out of sync, and I'm wondering if
something is happening asynchronously and it's screwing my ordering up.
Also, I had heard of some VM vendors re-building their bio stacks on top
of their nio stacks, has anyone used nio on Blackdown and what results
have you received?
 
(Am using bio in my code)
 
Kind Regards,
Max
