(rw,relatime,nospace_cache)
HDD graph is posted as reference. The oscillation is expected due to
media fragmentation, but internal fragmentation trend follows the SSD
findings for a fw initial reqrites. The slow write times are expected
due to random writes causing a 10ms head delay (500 secs / 4000 ops ~=
10ms for each write)
The SSD graph shows the actual problem better. The curves for rm, cp
and sync seem to follow the log(n) inherent design (B-tree search
complexty), but take too long in...

Compilation of R code
Hello,
I'm a newbie on this list.
