WinSock 2.2 API TCP/IP Protocol Driver for Windows
This release provides a new Windows TCP/IP protocol driver that takes advantage of the latest Windows Winsock 2.2 API. The new driver (tcp_ip) removes an architectural limitation of the previous implementation (wintcp), which resulted in a performance problem when a client application used many INSERT statements or a large number of single SELECT statements. Also, connection attempts sometimes failed when multiple connects were attempted simultaneously.
To allow a smooth migration from the existing protocol driver to the new one, the existing wintcp protocol driver is included in this release, but will be removed in the future. We recommend that you use the tcp_ip protocol driver.
