1. accessing a xerte object over a period of time
2. accessing a xerte object at the same time
1. is not an issue
2. is not a Xerte issue, but a limit (or configuration) of the webserver. No webserver will be able to enable an unlimited nr of concurrent users at the same time. The default is even dependent on the Linux distribution or the Windows version of the server. A typical number is 150 concurrent connectons at the same time (so not necessarily of the same LO)
