Another thing i notice is that i can override the automatic cache size and get rid of the disk overload when i crank it up to max (1800 MiB), but when a torrent is finished i get a "Flushing to disk (3388)" in the "Status" for that specific torrent. And on a side note uTorrent is eating up 15% of my i7 quad core, where libtorrent-based clients such as qBittorrent / Deluge only uses 2% max even when hashing and down/uploading. Btw I'm on win7 x64 with uT 26710. And as i mentioned earlier my hdd is not the bottleneck, i can do 100mbis up and down concurrent with qBittorrent and Deluge.
