Improve Cache performance

[Guest]

I want to improve cache performance in a special way.

I want it to read ahead on drive Y and Z.

Now I'm using different programms at once, and because they each read data
(dvd movies) from Y, Y get'sn incredible slow. You can hear heavy
head-movents.

Now I want to be able to use a tool if somebody knows one or change the
WINDOWS-CACHE behaviour.

That stupid windows-cache is a real pain in the ... .

It uses a lot of memory, while it hasn't to, and doesn't do smart things
such as reading ahead.

I can remove the fysical DISK OVERHEAD by using some kind of read ahead
mechanism. So if programm A uses Y, the Y-drive will be readed 100 MB ahead
for example. All file access is sequentially, so that would greatly improve
overall performance as far less head-movements have to be made to get the
data required.

My fysicall memory is 1 GB, so I can use it without problems...

Anybody on this ???

Anybody knows about (freeware) tools for this ??

I think it has capability of reading ahead. I made this
post 6 mos ago which went uncorrected:

In browsing through the posts I've noticed quite a few
regarding Safely Remove Hardware so I thought I would
offer an explanation of what is really happening that
altho conjecture is not contradicted by what I've
experienced with Windows 98, ME, or Windows XP. All
number crunchers that I worked on since 1967 worked
this way.

Double Buffering is where the OS sets up two buffers
in RAM for each disk. When you do your first write to
the disk you actually write in the first buffer and you
continue to write in the first buffer until it is full.
Subsequent rights go to the second buffer while at the
same time the first buffer is being written to the
disk. So in the steady state you're actually writing
to the disk and writing to the buffer at the same time
which is extremely fast. Indeed in experiments I have
done with removable drives they write twice as fast
where :

Optimize for quick removal = write drectly to disk
Optimize for performance = use Double Buffering

When you are all done writing chances are there will be
something left in one of those two buffers - Safely
Remove Hardware I think writes that buffer.

Double Buffering would also explain why a proper
shutdown is important - your current and correct
registry may be in RAM and needs to be written out to
disk before you shutdown.

My purpose here was to provide motivation for people to
properly shutdown and remove hardware which I don't
think anyone can have not knowing even part of the
reason. It's interesting to note that the Microsoft's
knowledge base has no articles with buffer in the
title.

Any advise is my attempt to contribute more than I have received but I can only assure you that it works on my PC. GOOD LUCK.
