Regarding this: OS overhead for network and file I/O etc.
Network I/O is on different threads. Not the primary thread.File I/O is also on other threads (both reading and writing). When an Intraday chart is updating, it is only reading from a memory cache. Not from a file. Although as historical data is being downloaded, the chart data is read from the file. When the download finishes, and the file reading is complete there is no more reading from the file. Sierra Chart Support - Engineering Level Your definitive source for support.
