> 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?
