--- Comment #2 from Robert Griggs rtgriggs@gmail.com --- In Wine 8.13, this is still an issue. SierraChart has added a workaround for Wine to use a single buffer but this still results in significant performance degradation.
Post #27 here: The issue is always with Wine. Wine has very very very inefficient handling of socket receive buffers and probably send buffers as well.
The simple fact is even with a single buffer, Wines network I/O performance is below 50%, or even lower, of what Windows provides, at least with the network I/O model that Sierra Chart is using which utilizes overlapped I/O and I/O completion notifications. Wines performance is absolutely terrible in this area.
