Wing Ftp Server 4.3.8 -

The server uses a multi-threaded architecture; each client connection spawns a separate thread. For very high concurrency (e.g., 5,000+ users), tuning the Windows I/O completion ports and adjusting the thread pool limits was necessary. Version 4.3.8 did not yet implement asynchronous I/O as efficiently as later versions, but it remained performant for typical business workloads (hundreds of daily users).
