I have talked to people using various gateways from mainframes to PC Lans, and none of them ever seem to be totally satisfied. I hear that Attachmates become erratic with high loads, and that Mitek is too expensive. The IBM TCP/IP offerings look great in theory, I should be able to use TCP/IP as my LAN and do all PC terminal sessions with a 3270 version of Telnet and all file transfers with FTP. BUT BUT---I hear that the performance of IBM's TCP/IP is not soo good. The 3172 connection from the LAN to the Mainframe doesn't do much work and so the Mainframe chews cycles managing IP packets. I have heard that the maximum throughput is 600Kbps. Is anyone using TPC/IP as an alternative to a typical PC gateway, and how do you like it? How is the performance working out for you? What has anyone else heard about the future performance of the TCP/IP products? I *will* post a summary if I get interesting responses.
