The Cache?
« on: January 29, 2011, 05:23:01 PM »
Does cache programs help anything with windows 7?

Such as -

It's more like to have some effect if your PC is low availble memory ... otherwise, what it can add to your system may be somewhat dubious.

Windows management of resources is pretty good these days.
Windows 7 SP1 (TM) Home Premium 64-bit .. Intel(R) Core(TM)2 Duo CPU P8400 @ 2.26 GHz / 2.27 GHz .. 4GB RAM .. NVIDIA GeForce 9800M GTS .. Gateway P-7805u FX

Thanks, I have enough memory but a 6 year old computer.
I figured it to be using more resources then I it would save.

Let 7 handle that but if you have old and expensive ram to spare you could investigate advantage of a Ramdisk. You can easily throw more at ramdisk with help of tools like Junction Link Magic More so if you believe in everything counts theory ;) In most cases it will probably be better to let Windows handle ram/cache. I use Vista and it stinks with SuperFetch cache but 7 is much better. Pretty sure you need special requirements to warrant tools like that O&O thingy. Ramdisk does work if you have plenty of ram though.

Look at CleanMem http://www.pcwintech.com/cleanmem if you believe in O&Os idea of "and thereby increases available main memory resources" Free...

Yes, I've tried CleanMem, and it slowed the response time of Firefox then.
Now it's at version 1.6 so I may try it, just to see.
Works different then a cache type program I think.

I wasn't going to buy OO's product, but wanted to know about the cache.
(It has been a 'giveawayoftheday' at version 6 before, just preparing for it to come up again.)
Which, I guess is something like virtual memory on the hard disk.
I'm not sure, so hence the quest-ion.

Doesn't Outertech's Cacheman do something along these lines?

http://www.outertech..._page=news&id=58

I'm just not so sure about messing around with how my system normally works.
And then have to restore it to it's built in, native, in place already functions.

Know what I mean? :)

No I don't know but that does not stop me from posting :D Both of those you mentioned, and CleanMem, seems to be more about memory management than disk caching. O&O also have a buffer/cache for file operations though. But to free up memory which Windows holds back from being used is the message. As you can see from picture at O&O site less caching is considered a good thing because then there is more available ram for your programs. I wonder how CleverCache can handle SuperFetch other than simply turning it off?  

O&O Mem-O-Safe seems to be related to FancyCache which is free (for now at least) http://www.romexsoft...ncy-cache/index.html  Read about it on their forum before installing. If you use partition version, activate it for C: and give it a long wait (Defer write/latency) to really use buffer effectively what happens if Windows go BSOD? Do you feel lucky or not? Effect is similar to a normal Ramdisk but potentially worse since FancyCache buffer/hold all types of data, you cannot tell it what to include/exclude. Definitely read about it first but it does work. I have used it for a while but not yet 100% comfortable with the idea. Pretty sure I will return, keep eye on it for now. Judging from their forum most people have positive experiences, especially those with SSD seem to be going crazy. Long thread on this SSD forum http://ssdtechnology...highlight=fancycache Might do wonders on old system with enough ram.

Seems like OCZ approves and is involved to some degree http://www.ocztechno...iewfull=1#post598218

I have not tried this but if you have no ram to spare FancyCache can use external disk for caching. Like using an SSD to cache old slow hds http://www.romexsoft...c.php?f=25&t=694 Should also work with a flashdrive, a bit like Readyboost I guess http://www.romexsoft...mp;hilit=flash#p1385

Also you can play around with ntfs file system cache using command line settings:

http://www.howtogeek...cache-size-in-vista/

running this command will tell you the current setting:

fsutil behavior query memoryusage

After setting this param a reboot is required.
(You change the setting by using "set" instead of "query")

CleanMem cleans file cache system like CacheSet (by Systernal) does.

To disable 'Last Access' files feature could avoid many file accesses in System:

In command line:
fsutil behavior set disablelastaccess 1
OR set to 1 in Registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem -> NtfsDisableLastAccessUpdate=1

NtfsMemoryUsage debunked? http://www.tweakhound.com/blog/?p=1164

I think Last access is actually disabled per default in Vista/7 majoMO

CleanMem does more than CacheSet from what I can tell. Not so sure about value though. Author seem to be careful not to promise too much, probably wise.

It may vary with the Windows edition.  For Home Premium you may have to explicitly set it.

Possible, I only have Ultimate versions of Vista and 7. I checked long time ago because I read that is should never ever be disabled with SuperFetch enabled so went ??? seeing it was already. MS does not mention this connection but hint disabling can give problems with some backup software, may be also cleanup/disk tools like MyDefrag http://www.mydefrag....astAccessUpdate.html

You are right some backup software about, Bamse. Last acess disable related. Like to uncheck "Allow Indexing Service to index this disk for fast file searching" couldn't be good if the user needs to search for files very often. However I think that, in general, there hints could be good for the system performance.

MyDefrag about: their defaults scripts don't use the "LastAccessEnabled" action; users can do their own scripts with it though.
