so, what can the arduino IDE be doing to generate this much i/o activity in a antivirus program??? i am wondering if it is an 'odd' behaviour of the arduino IDE - not necessarily a bug, but perhaps just something unexpected - exposing a bug that exists in panda (and potentially other antivirus software).
simple it uses java
java always triggers an immense response in av programs. i noticed that again and again.
i think it has something to do with classfile loading by the vm itself. on startup it reads a lot of classfiles since they belong to the api. each file must be inspected one at a time. since this is done via online link this takes extra time for the response to be received.
btw: startup delay is somewhat related to processor speed and amount of ram in the system. if loading the ide triggers massive swaping due to low ram, hdd transfer speed also becomes a bottleneck. so with a recent machine (lets say 3 ghz, 2-4 gb ram) i doubt there will be any delay felt at all.
