At 1st i had not checked this option which causes my mac to hang due to lack of memory, nothing helped and i was forced to restart my mac by holding the on/off switch.
Downloading at 56MBs is simply too fast for my NAS to which i download the files.
Enabling the write buffer worked and i can download again normal without my system hanging.
The downloads will stop at some moment to wait for the flush disk....
Again... usenetic... Very Goooooood.
