Were you sure to remount your devices to clear the cache before running
these tests? While testing this patch early on the cache caused me many
incorrect readings. Another approach I took to clear the cache was to fill
up all of my RAM with some other process.
To clear the caches you can use
echo 3> /proc/sys/vm/drop_caches
In my testing I left the inode cache alone
for my mechanical disk and used:
echo 1 > /proc/sys/vm/drop_caches
For spinning the CPU I just used:
openssl speed
