Dear Engineers, I have started working on a lustre file system. I have done a couple of experiments so far: On the first experiment I am writing 100 files each 10MB and the batch size is 4K. I got *704MB/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 write bandwidth is *697MB/s* while read average bandwidth is *380MB/s* which is very weird I guess? Experiment files are on : *https://github.com/nagmat1/lustre_installation-experiment <https://github.com/nagmat1/lustre_installation-experiment>* I am using FIO as workload generator : *https://github.com/axboe/fio <https://github.com/axboe/fio> * 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 *10000Mb/s.* Kind regards Nagmat Nazarov
