With 4KB blocks, all reads, either random or sequential, performance is 20MB/s, this doesn't seem too bad considering the difference in block size, but with all writes the performance plummets to under 1MB/s. One surprising good result, using 2 separate disks, with two worker threads, and 1MB blocks, all reads or all writes, either random or sequential, the total performance is 180MB/s. _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
