[ECOS] Performance comparision

Hi,

I am the same guy who asked about the problem of having a very high tick
rate for addressing very small time units.
I now perfectly understand the futility of increasing the tick rate to very
high value and have decided to use external timers to address small time
frames.

But just for comparision, I ported my application to VRTXsa a different
RTOS. And I used the same high tick rate ( about 10000 ticks per second) and
the application was running fine. I was able to acheive the bit rate of
about 20Mbps that I was suppose to acheive. But in eCos with such high tick
value I was able to acheive only 4Mbps.

In reply to my previous mail I understood that if we use a very high tick
value a lot of processor resources will be spent on processing the tick only
and my application will suffer. But why am i not facing the same problem in
VRTXsa?

Is it a limitation of eCos?

Thankyou,

indrasena
