Hello together, very interesting. i switched to xfs filesystem. But same situation. For my proposes both filesystems are perfect fast. Then i did a benchmark with command 'dd' Tried with 'dd if=/dev/zero of=/share/mounted_glustered_dir/test.img bs=1M count=1000'. Perfect write speed! Also at the replicated peer. 500MB in perfect less than 10 Seconds, also at the replicated peer. But when i copy many files from a to mounted glustered dir, then the write speed broke into KB-Range. Any clue what this can be?

After the file is written nothing happens for 1 or 2 seconds.
