And are there negative points to this? (else it would be standard active I think iin the kernel....?)

[Was_Just19]

Is there some simple means of determining what is being used in a running system?
For instance if this boot code is used can one determine if it is in fact in operation from some simple command?

=> deadline, CFQ, ....

Don't we use BFS (as the best possible one) - or do I see that completely wrong???
Or is this an option that can be added to the BFS one?

I must admit this little trick improved the speed of usb. I have a64 kernel so my Brain is not Fooled by that Scheduler. 

[Was_Just19]

Thanks for the response .....  cannot say I have noticed any difference as yet .......

Code: [Select]

[user@Dell ~]$ cat /sys/block/sda/queue/scheduler
noop [deadline] cfq

[rubentje1991]

OK, thanks for all info,
Now I'm not afraid anymore to try using it...
(if it would give a bad result, I always can modify it again

I've had an issue with usb transfers.  They'll start at a good speed, then slow, then speed, then slow.  Transfers take 4X the time as Vista.

I tried this tweek, and for me it made no difference. 

It didn't hurt either  ;-)

So the following command:

Code: [Select]

cat /sys/block/sda/queue/schedulershows this:
noop anticipatory [deadline] cfq

[Roc4fun]

That's right.  I'm definitely using the deadline scheduler.  But in my case it made no difference.

[dave@localhost ~]$ cat /sys/block/sda/queue/scheduler
noop [deadline] cfq
[dave@localhost ~]$

[kizito]

[dave@localhost ~]$ cat /sys/block/sda/queue/scheduler
noop [deadline] cfq
[dave@localhost ~]$

On my machine (PCLinuxOS LXDE 2010), without making any changes ...

Code: [Select]

[muwawa@localhost ~]$ cat /sys/block/sda/queue/scheduler
noop deadline [cfq]
[muwawa@localhost ~]$
I wonder why the '[ ]' are on 'cfq' for me instead of 'deadline'?

.....  because you didn't make any changes ?? ?? ??

[gseaman]

That is funny, I'm going to call it the Brain Fooled Scheduler from now on.

I don't care if it's the placebo effect, if my symptoms are gone!

Ah, I hadn't figured it, the bracket go round the applied function.
