Sending multiple pages in single WRITE command does seem to help a lot with performance. I modified code to write only one page at a time and ran a fio job with sequential writes(and random writes), block size 64K and compared the performance on virtiofs. NAME WORKLOAD Bandwidth IOPS one-page-write seqwrite-psync 58.3mb 933 multi-page-write seqwrite-psync 265.7mb 4251 one-page-write randwrite-psync 53.5mb 856 multi-page-write randwrite-psync 315.5mb 5047 So with multi page writes performance seems much better for this particular workload. Thanks Vivek
