This can cause unexpected behavior under certain circumstances. When your program changes the state on a specific pin, for example RB0 in PORTB, the PIC microcontroller first READs all 8 bits of the PORTB ... earp\\u0027s seafood prices

WebJul 21, 2016 · 2. You have set ashift=0, which causes slow write speeds when you have HD drives that use 4096 byte sectors. Without ashift, ZFS doesn't properly align writes to sector boundaries -> hard disks need to read-modify-write 4096 byte sectors when ZFS is writing 512 byte sectors. Use ashift=12 to make ZFS align writes to 4096 byte sectors.
