roi_counters during continuous fast scan are not read fast enough and that can corrupt the data
On ID22 we experienced a problem when running the fastscan on motor tth and eiger detector and reading 9 roi_counters. The roi_counters during the scan are not plotted and at the end of scan we can see corrupted value of the roi_counters. We did try to increas the BufferSize of the roi_counter device server but it did not help. For info on ID22 the scan are running the acquisition between 500 and 1000Hz and for at least 20K up to 100K points.
