I'm doing random readings of 4GByte files with the FIO tool. Gluster reading speed is of 150-160MByte/s and 110-120MByte/s per client if I connect with two clients. However, on the same machine, I have a similar lustre setup with a constant 400MByte/s throughput, for the same tests, with the same amount of disks going through the same RAID controller. Both tests were ran at different times. As comparison, for the...
