[Vtigercrm-developers] what's the purpose of scheduled import?

[lucia digirolamo]

I never understood why vtiger automatically schedule imports above 1000 
records. I find this limit to be too low and besides, should I be the 
one to decide whether it is best for an import to be scheduled? I hoped 
this limit would be increased in vtiger 7 but it's still there, so 
there's must be a valid reason to have this kind of automatic behaviour. 
Anybody knows why? And if it cannot be removed, is it safe to change the 
frequency of scheduled import from 15 mins to less (maybe 5 or even 
every min) ?

NOTE: this is not intended as a complain, I'm only trying to understand 
why things are done this way and if I'm the only one that finds this 
feature un-helpful
