Dear Engineers, I have started working on a lustre file system. I have done couple of experiments so far: On the first experiment I am writing 100 files each 10MB and the batch size is 4K. I got 107MB/s bandwidth.
On the second experiment I am (writing 10 files each 10MB and reading 1 10 MB file back) for 10 times. Here also the average bandwidth is 106MB/s while read average bandwidth is 59MB/s which is very weird I guess? My question is, generally on ext4 file systems read average bandwidth is faster that write average bandwidth, why is it 2 times slower on lustre file system. My ethernet speed is 1Gb/s. Kind regards Nagmat Nazarov
