Applies to: Syncplify.me Server!
Version(s): 4.x - 5.x


Introduced in v4.2, there’s a registry setting that allows Syncplify.me Server! to automatically choose the socket’s inbound and outbound buffer sizes in an attempt to optimize upload and download speeds.


This setting cannot be configured in the web interface, the only way to set it is at the Windows registry level. Restarting the Syncplify.me Server! system services are not necessary, as this setting is pulled from the registry every time a new incoming connection is served. 



The value name is  AutoOptimizeSocket and the type is DWORD. Setting this value to 1 (one) activates the automatic socket buffer size optimization while setting it to 0 (zero) disables such automatic optimization. If the value does not exist the optimization is disabled.


Please keep in mind that many pieces of network equipment (routers, firewalls, access points, …) already perform a great deal of speed optimizations, so you might very well not need to enable this setting. But in some cases, it might be useful, for example when you can achieve very fast file transfer speeds over the Internet but for some reason not in your LAN or vice versa.
