JDE recommands at least 50 Mb RAM per user on WTSE servers, but this is clearly to short. Think about 100 Mb RAM per user, this would be better.
It would be better with two servers with load balancing, but don't forget load balancing in WTSE only examines the number of connexions and not really processor or RAM charge on the servers.
We've had many pbs with undersized WTSE here, especially with many crashes of user sessions, resulting in fantom lines written to JDE files. My WTSE are 866 Mhz bi-processors with 1Gb RAM. Itried to simulate an increase of the server charge by connecting many "sleeping" user sessions, ie opening JDE and one heavy program such as P4210, P4310 or P0911 for each fonctionnal domain. With 13 opened sessions, RAM charge was 80 % without doing anything else. So be carefull with hardware capacities. Not that increasing swap file doesn't solve anything.
You may encounter other pbs with WTSE, concerning printer configuration for users. It's not really fonctionnal.
You may prefer work with Citrix Mainframe, but this is an expensive soft. I was proposed to install a web server instead of WTSE, for the reason it becomes now more stable than WTSE (requesting less hardware capacities on server and lighter for bandwidth).
Hope this would help u.
