Terminal output

We have a code which is working fine for years on Windows OS, but on Linux
using Wine it produces an IO error. Investigation shows that IO
Completion/Overlapped of Wine provides some buffers with received data out of
order. Our code relies on correct order of the received buffers.

Our code provides to OS some minimum number of buffers available to receive a
data. We expect the FIFO logic of the buffer processing: the first provided
available buffer will first receive the data.

Invoke `WSARecv` with a buffer to receive data. The operation is overlapped
using Completion Port.
In a worker thread the function `GetQueuedCompletionStatus` is used to get the
completion notification about received data in the buffer. At this point we
observe a buffer, received out of order. Usually it is happened at beginning of
handling buffers: we provide to OS some set of buffers (in common 16), handle
all of them with received data, reuse available buffers again to OS to support
the minimum set of buffers for OS and most probably the first (or close to
first) reused buffer will be received out of the order.
Also we observe the out-of-order buffer is returned in the same time slot as it
was issued to OS.

Relevant WindowsOS functions used:
CreateIoCompletionPort
WSARecv
GetQueuedCompletionStatus

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.
