an option to turn it off could be usefull,

but the problem you mention above should be handled transparently by the 

the ajax in the application is responsible to interact with the customer 
- not the server - so the ajax has to handle delays and take proper actions.

is see no difference in waiting for ajax to transmit and recieve data - 
or waiting for a whole page to be loaded after submitting the form ... 
the only difference is that loading the whole page will even take longer 
than ajax loading only relevant data ...
