Is there a way I can benchmark tmpfs

Question

I created a tmpfs which was mounted at /ramdisk using the mount command.And I tried to benchmark this tmpfs using something like this:

hdparm -tT /ramdisk

And I was told that /ramdisk is a directory.But apparently there isn't a corresponding device file under the /dev directory for the tmpfs I created. So is there a way I can benchmark this tmpfs?

Thanks

I'm trying to use this tmpfs for apache2 disk cache.And I want to make sure that tmpfs is better than vps hard drive. — Steven Jang, Apr 21 '13 at 13:23

Take a look at this

In your situation:

Test writing speed: dd if=/dev/zero of=/ramdisk bs=4k count=10000

Test reading speed: dd if=/ramdisk of=/dev/null bs=4k count=10000
