Hello everybody, I''ve finished with pci export from DomU to Dom0 (Debian Etch) but now i have a new problem, and a big one. My ethernet card is dropping packets but after some time (i can''t tell how) It can work for a day (not in production so not hard tested) and then all packets are dropped. Look at the ifconfig output : eth0      Link encap:Ethernet  HWaddr

Hi, all This version reworked on REQ_FLUSH and REQ_FUA support as suggested by Christoph and dropped the block core bits since Jens has picked them up. Fio test shows bio-based IO path gives the following performance improvement: 1) Ramdisk device With bio-based IO path, sequential read/write, random read/write IOPS boost : 28%, 24%, 21%, 16% Latency improvement: 32%,
