I have attempted to use a tmpfs to speed up some heavily accessed files. I wanted to test the read and write speeds of both the HDD its self and a tmpfs. My results where strangely low for what I was expecting:
dd if=/dev/zero of=/home/******/tmpfs/test.data bs=1k count=128k
131072+0 records in
131072+0 records out
134217728 bytes (134 MB) copied, 4.03752 seconds, 33.2 MB/s
/home/******/tmpfs is a 200MB tmpfs that I mounted a little bit before.
I do not have much experience with tmpfs's and was wondering... Isn't this very slow? What can be done to speed this up? What is causing the slow speeds?
