For disk io may be you can try something like this:
$ dd if=/dev/zero of=/tmp/testfile bs=1G count=1 oflag=direct
1+0 records read
1+0 records written
1073741824 bytes (1,1 GB) copied, 6,9191 s, 155 MB/s
Change the "bs" to something smaller if you're testing slow / small disks.
Make the "of" a file on the filesystem you want to be testing
remember to remove the testfile afterwards
sometimes the /tmp folder is not actually on the disk (e.g. it is a mounted ramdisk), so choose an appropriate location for testing.
You could test read speed by changing "if" to an existing file and "of" to /dev/null
Lol....you completely lost me, I am not a coder or do I understand much or what you have written...
Maybe something much simpler...
