Re: hard drive speed up?

I have been using noatime, works fine.
I will set nodiratime too now, didn't know that existed.

Do these work for XFS too?

EDIT: man mount says XFS can do noatime. I guess it can't hurt to just put both of these for all filesystems.

Re: hard drive speed up?

Think it relates more to ext3... atm all I have in fstab is defaults

Well that's an old trick, but yes, it helps a lot.

No no, thats just the things ppl automatically do when installing...

I think even ubuntu has that on by default. Afaik noatime is enough, nodiratime comes with it.

Re: hard drive speed up?

Latest ubuntu seems to have relatime and .... I didn't know about this (guess I didn't read the wiki properly or it got changed meanwhile) .... I'm starting with relatime and see if everything keeps working as it should (I suspect it will) then I'll move on to noatime,nodiratime.
I've read that noatime is a superset of nodiratime but by reading the man page I get the feeling they are two separate things and you need to use both to do the trick.

Re: hard drive speed up?

Yes I know, I asked a friend that is trying ubuntu to cat his fstab
But I've moved to noatime,nodiratime. No other options besides the defaults and it seems to be working very well. Fam doesn't seem to hang that much (at all) now but thats something for another thread I guess.

Re: hard drive speed up?

Does this procedure mean anything when applied to raid0 array made up of three CF IDE cards?

Re: hard drive speed up?

Yes, if for every file you read you need to write back the last access time then it doesn't matter what kind of setup you have. It may be just less noticeable if the storage subsystem is faster (which is your case with raid0).

Re: hard drive speed up?

I was using option noatime for my JFS partitions for quite a time, but haven't heard of nodirtime till now. Will see if it changes anything.
Anyone know a good HDD benchmark for Linux?

Re: hard drive speed up?

relatime is techincally the most compatible option. noatime implies nodiratime so its pointless...

edit: and afaik there are no fs benchmarks for linux, there are plenty of hdd benchmarks but I dont think thats what you meant?
People tend to just copy around files, time it and assume that this has some real world relevance to the FS performance
