[Samba] Asynchronous I/O

[Andy Liebman]

Hello,

Is there any straightforward way to see whether Samba is using 
"asynchronous i/o"?  In other words, if you specify in smb.conf to use 
aio for all transfers larger than 1 KB (pretty much everything), how can 
you tell that aio is actually being used?   Are there any counters in 
Linux or in some samba logs that you can see incrementing over time?

Thanks in advance.
