Hi all,
Just a quick question! I'm running an app which is used for testing
i/o. Right now, I'm running a thread at an elevated priority which
does a lot of pread() calls. The app works fine but is a little slow
& right now, I'm fine-tuning it. One issue, though; when I fire up
BigTop, find my process and look at the system call throughput, I
notice that it appears to be capped at 9000 calls/sec. I'm guessing
this is being throttled by a kernel parameter. Is there any way this
can be modified? I can understand why there is an upper limit on
something like that, but I don't mind if my particular app/thread
dominates the machine. The device I'm hitting is more than capable of
beating that, so I'm definitely not saturating the driver. Thoughts /
hints / ridicule welcome :-)
Best regards,
Allie
