Okay it sounds like crazy, but I will peform user test with kids using istoa client on XO laptops.
The connection to the server (a laptop, cable connected to a wifi access point) is done through wifi as it is the only network link to a XO laptop. The connection time is pretty long, next the remote use of the Magma database seems ok (performance and only one error).
So far it takes about 90s for a XO laptop to open a session to the Magma database. I have enclosed a MessageTally spyOn when the session is open. I will be happy to get some feedback about anything I could improve regarding this benchmark.
But any way running on the XO is pretty slow.
