It has been a struggle with the nand performance on QNX with etfs filesystem. On the same board, ubifs on linux gives better performance.
one experiment observation is below…
cp /tmp/4M.cp /test_dir/4M.cp
Linux: 81.63 MB/sec
Qnx: 5.41 MB/sec
cp /test_dir/4M.cp /tmp/4M.cp
Linux: 105.26 MB/sec
Qnx: 9.09 MB/sec
[got these speed by formula of size/time consumed; here size = 4M and time collected from time command in seconds]
i am wondering, if etfs can match up to ubifs performance. if yes, then how ?
Is there any benchmark for etfs file system? i couldn’t find any reference.
Or is there a better way to compare the performance b/w these?
