Readyboost

[Jurij]

Hello all,

I was intrigued by the Readyboost feature, but I presume it's more effective
on
"resource limited" systems?

No - ReadyBoost helps the performance of all systems as acting as a faster
write through caching area to the hard drive.
So even on systems with plenty of memory where there is any writing to disk
and then potentially reading that data back in (after it may have been
flushed from memory) then the use of the ReadyBoost cache is faster then the
access to disk.

 

[carl feredeck]

Experience shows that readyboost does nil for computers with lots of ram.
Some people here even reported that it slowed their high end computer down!

YES readyboost also has a bug noted to be fixed in the SP1... but that will
be around the end of the year!

Basically readyboost is a bad idea and a "patch" technology to go around
actually writing the vista code better leaner faster and smarter.

Basic MS logic: Lets bloat vista to smithereens, don't waste time actually
thinking, and then lets add a readyboost to make everyone happy.

WHAT A DISGRACE! You have been brainwashed and you love it!

Even a PC with a lot of RAM will flush unused entries from cache when an
application exit. Say for example you were doing some work in a word
processor package.
If you subsequently reopen the application and open the document you were
working on this will be draw from the ReadyBoost cache significantly faster
then from the hard drive. That is a performance boost even for a system with
a lot of memory.
I run systems with 4 and 8GB of RAM and there is still performance to be
gained by using ReadyBoost.
On laptop systems I un with 2GB of memory a 2 or 4GB memory stick again
improves overall performance for day to day use.

YES readyboost also has a bug noted to be fixed in the SP1... but that
will be around the end of the year!

So? There are a number of outstanding bugs in the OS that re being
addressed with the monthly patches and will also be in SP1. This does not
mean Ready Boost should not be used.
(If you mean 939008 then this is not even that big a deal)

Basically readyboost is a bad idea and a "patch" technology to go around
actually writing the vista code better leaner faster and smarter.

Not at all - it is actually an enhancement as hard drive technology and
performance is being out stripped by solid state "drive" technology :
ReadyDrive goes on to use the similar technology for Hybrid drives which are
actually a patch again to slow spinning hard drive technology by
incorporating flash drive memory into the drive.

Basic MS logic: Lets bloat vista to smithereens, don't waste time actually
thinking, and then lets add a readyboost to make everyone happy.

Again incorrect - this is helping the performance of the system until
everyone can afford to switch to solid state drives of sufficient capacity
etc.

WHAT A DISGRACE! You have been brainwashed and you love it!

No brainwashing here - it is you with your ill informed and ill conceived
arguments that cannot see the real reasoning behind this technology or where
it can and should be used.

Your real-world experience seems to differ from mine and *many*
others, including a lot of MVPs. Perhaps, you are used to quoting
what Readyboost is supposed to do, but most of the comments
in this forum- now and since the betas- ReadyBoost has *not* provided
any noticeable improvement on machines that have over 1.5 GB of Ram.
The only times I have noticed a *little* bit of help from ReadyBoost is
when I run virtual machines. There have also been a few sites that have run
some tests on ReadyBoost, most of it's not very flattering. About the
only time ReadyBoost shows any *noticeable* improvement are in
system with a Gig or less of Ram.

My findings are about the same on three different Vista machines.

Readboost was NOT designed for systems with large amounts of RAM; simple as
that!

I have read that readyboost will come into its own once the operating system
is modified to take full advantage of this approach. I will wait and see
what is reported by others before I invest.

yeah ok, MVP's are not really 100% alive.
they are un-dead or brain dead (there are some exceptions in other
newsgroups but no good ones in this newsgroup). Dont mention them as a good
example!

Opening a File or Application is noticeable faster from the cahe of ReadyBoost than the Hard Drive. This I have seen on machines with 1gig of Ram as well as 4 Gigs of Ram

 

[carl feredeck]

I will try an experiment and see....

How much faster is a USB2.0 flashdrive data transfer in comparison with a
hard drive disk? Any numbers?

Carl,

It's not just MVPs who have stated the uselessness
of ReadyBoost on machines with RAM over 1.5 Gigs.

It depends a lot on what you're doing. I have 1 gig RAM and
saw no noticeable speed increase. In fact it seemed to slow
down booting and shutting down quite a bit. The following
article/link gives a couple of examples.

I know.. if you read my original reply to mike I say the same exact thing.

Readyboost effectiveness is most apparent on machines with 512 megs of RAM.

hi
i use a compaq presario notebook 1gb ram ,vista hp . i used it for about
3months before i bought a 4gb usb stick and started using ready boost i
noticed a difference straightaway (for the better)but having looked into
readyboost i can see that a lot depends on the transfer rate of the stick ,a
4gig stick can still have a slow transfer rate rendering it useless for
readyboost even slowing higher ram systems down

Once again: Readyboost is not associated with system RAM. ReadyBoost works
in concert with Superfetch the replacement for Prefetch (previous Windows
version).

Whether or not Vista will designate a device for ReadyBoost depends upon
comparison read/write characteristics of the HD and the external device
(there are minimum specs).
There will be no ReadyBoost gain if the Win performance index of the HD is
"5" (maximum rate is 5.9) - which is why ReadyBoost is significant for
laptops with slower HDs.

Non-sequential read/writes are "sent" to the ReadyBoost device (or cache)
and sequtntial read/writes to the page file - meaning that performance will
also depend on the type of HD activity.

An internal ReadyBoost cache is in use whether or not there is an external
device. Also of importance - ReadyBoost (via Superfetch) over a period of
time monitors application activity and adjusts performance accordingly.

I concur ... but I didn't always.

I was not originally a fan of ReadyBoost, and even made it known here during
some early trouble with this laptop when it was fresh out of the box. But
I'm starting to think I may have been a bit premature.

I quit using RB for three + weeks during a period of intensive CAD while
designing a new kitchen. You get a real good "feel" for the responsiveness
of any system during long hours of such intense daily use for that long a
time.

Just for grins I recently decided to give ReadyBoost another shot on an SD
card.

The responsiveness of this Dell XPS 1210/2GB RAM/160 GB SATA 5400rpm HD is
_noticeably_ improved with an 1810MB RB file on this SD card.

I'm sure this is a classic YMMV, but there is NO doubt about the current and
noticeable improvement on this box.

That said, we'll see if it eventually corrupts this media like it did the
first time I tried it on a high speed USB thumb drive.

Well ... what using ReadyBoost does cause on this box is shutdown problems.

On the next three out of five shutdown attempts the machine stalls at the
shutdown screen and has to eventually be powered off.

A Google search indicates that this is not an unknown problem with
ReadyBoost as a number of folks experienced the behavior with various RC's.

I had that trouble as well as sound and other issues. Not only did I have
to stop using ReadyBoost, but I had to reformat to set things right again,
could not even go back in time to fix things.

USB2.0 High-speed Flash Drive: 10-30mb/sec
IDE Data Transfer: 133mb/sec
SATA Data Transfer: 150mb/sec
SATAII Data Transfer: 300mb/sec
