How to increase system system performance
I have never seen any evidence or even ever heard of Windows creating any
"Temp" files on any drive when loading an application. If you run Excel it loads excel.exe in memory and then loads or creates a new .xls spreadsheet file in memory there are no other/temp files created. "Tae Song" wrote in message ... "Pegasus [MVP]" wrote in message ... "Tae Song" wrote in message ... OK very last post on this subject... hopefully. I'm sorry I don't have benchmarks to back up the any claim... I'm just too lazy to do one and I can't seem to find a free storage benchmark program that I like. Actually I don't really care, I just like this setup, it works for me. Not very scientific but there you go. In other words: You like the slow-down you designed for your machine and you insist telling everyone about it, dressing it up as the greatest thing since sliced bread. Do you really expect anyone to believe your claims when, by your own admission, you're too lazy to verify them? I thought up a better way to illustrate my point, so I didn't resist posting this... shame on me. When loading an application, Windows reads files from the hard drive into memory while creating temp files. That's read throughput (hard drive) + write throughput (USB drive) is greater than the throughput of hard drive alone. It's not a competition about which drive is faster. And read and write operations described previously can occur side-by-side, where as on the hard drive read and write would have to be queued. (Temp files on flash drive) USB ++++* HD ---------- (Temp files on hard drive) USB HD --o++------- o = overhead for extra seeks associated with having the temp files on the hard drive. * I put in an extra ++ for temp files on flash drive since writes are slower and also to illustrate why it doesn't matter. I did think up of what I thought was the best way to benchmark and illustrate the performance difference. It requires the setup of identical hardware to isolate any variables down to just the temp file locations. It would be preferable to have one set of input devices for both computers so they are getting the same input at the same time. But I just don't have that kind of money. Anyways, even if I did tons of benchmarks on MY hardware. It doesn't mean you will get the same results on YOUR hardware. You will just have to test out the idea for yourself, unless you don't want to find out on your own. |

How to increase system system performance
I understand that current releases of some office products create temp
versions of their own documents when you start editing them. But it is the application program(Word) creating them and not Windows itself as Tae Song claimed. "Gordon" wrote in message ...

How to increase system system performance
Excel does the same thing.
A temp file is created for each workbook opened. When the workbook is closed the temp file is deleted.............most timesg With a workbook open browse to C:\Documents and Settings\username\Application Data\Microsoft\Excel You will find an ~123x456.xar file Gord Dibben MS Excel MVP On Sat, 13 Jun 2009 16:12:34 +0100, "Gordon" wrote: "Curious" wrote in message ...

You are correct. I should not have used an Office product as an example of
what happens with any Windows based application since the Office applications themselves create temp files as you describe. "Gord Dibben" gorddibbATshawDOTca wrote in message ...

How to increase system system performance
"Tae Song" wrote in message ... "Bill in Co." wrote in message ... Tae Song wrote: I thought I would share this with you all, a few little tricks to boost Windows performance. If you have a spare USB flash drive or you are willing to get a cheap say 1GB flash drive. First we plug in the flash drive. Go to Disk Manager and assign it a drive letter, like Z: (this is just to get it out of the way and optional) Go to Advanced system settings, Evironment variables. Change the Temp variable under User to Z:\ (I didn't see any point creating folders, but that's optional) Change the Temp variable under System variable to Z:\ This will cut down on I/O traffic to the hard drive. Starting an app like Word, would cause the HD to read the program into memory while at the same time writing into the drive, temporary files. This causes an I/O queue to form and degrade Windows performance. By off loading some of the I/O traffic to another storage device, the hard drive read/write head doesn't have to move around as much either. All performance gains. I don't think so!! There will be a performance LOSS, in large part due to the much longer write times to a flash drive. Also, it's generally a poor idea to have so many continuous writes to a flash drive, as flash drives have a more limited number of write cycles. snip rest of this post You don't need an extremely high write speed. A lot of times temp files are just empty files, many are 0 bytes. Almost all are under 700KB. Even at a write speed of of say a low of 5MB/s is still only a fraction of a sec. This keeps the read/write head from thrashing about creating and updating file records. And just to up the ante, I enabled disk compression on the USB drives to reduce the size of the writes. Reducing the size of the writes won't affect the time it takes and certainly will not alter the fact that Flash technology has a limited number of write cycles. If you're using it as a temp drive, you are ensuring that a flash drive will fail *sooner* rather than later. Flash drives aren't appropriate for filesystem utility use. They can only be relied on for convenient transfer of data that exists elsewhere. |
