When I use an external drive via usb, my computer really slows down giving me no choice except reboot.
I watched memory usage with activity monitor. Free memory decreases by time and inactive memory increases with the same amount and others don't change much. If I continue using -esp. reading-, free memory comes below to 100MB and then increases a bit -I think it starts paging =other applications' memories= to system disk-, then continues to decrease. Closing the application -that use the external- do not relese memory from inactive to free but ejecting the external does. After unplugging and trying to use the other applications, I face very sluggish performance so that rebooting becomes a better-fast choice. Both NTFS and FAT partitions produce the same result and I don't have any other partition.
If I try to re-read the same file after the external drive stops spinning (sleeps), it does not start spinning but trying to read another file makes it start spining. This makes me think about some -overdone- caching problem, but don't know what causes it and how to turn it off (Tuxero's caching is already disabled in the preferences, although I think it is only for writing only).
I made some research and found nothing specific; they tell to reinstall the os or format the drive -to HFS+ -. What is causing this?
Note: All of my drives are in Spotlight's exclusion (privacy) list and using another usb slot did not change a thing.
