The reads should be interrupt driven. Otherwise, this is where a RT operating system should be useful.
They are event driven. No polls here. But still, the handling process needs to run. When indexing as discussed is not happening, this works great. It is, I think, the disk activity that is the issue. The system is quite active when the disk is busy for indexing. So even if an application can run, some resources seem to slow everyone down. So we also turn it off.
Event driven is good enough for desktop things, not for data acquisition. If you have software that requires operations to happen at certain times, no matter what, you have to use either a Real Time OS (and use its facilities) or use interrupts to drive those operations. No matter how busy the system is, those operations have to run on time. Otherwise, the system will run ok on certain circumstances, with no guarantee of when it fail to be there on time. - -- Cheers, Carlos E. R.
