SSD noatime Increase drastically performances
Well i was reading something and i came across a hint, where it was stated that if your Dedicated has a SSD hdd and has the atime active which is a timestamp for inode that will display the last file access, well if you disable it your hdd performances will increase.
This is because when you are accessing the file each time, the system has to update the index and thus will decrease the hdd performances.
you can disable the atime in fstab with noatime :)
I hope this help someone.
