Guest flahmeshess Posted August 6, 2007 Posted August 6, 2007 I have 2 disk. HDD1 has - C: OS - D: applications - E: data - X: temp data HDD2 has - not use - F: data - Y: temp data I created a X: drive which is at the end of 1 HDD to put but I wonder if that is the optimal place to put it. Should I put it in Y: drive which is separate from my OS ? Or should I put it in C: ? My problem now is that since I've added the HDD2 (which is 500GB), my system hangs when going to standby. I don't know if it's due to HDD2. Thanks.

Try putting it on your C: drive only and see what happens
Guest Joshua Bolton Posted August 7, 2007 Posted August 7, 2007 RE: Where to put swapper file ? Partition type doesn't matter. It could be on an extended partition. For a server you would move the pagefile to the 2nd hard drive. This way disk io access isn't be competed for by system and pagefile operations. Optimally drive2 is on the second ide channel. Some MS articles would suggest you leave a small pagefile on c: for if there is a crash dump [debug info]. My response is to ask the question when was the last time you fixed a problem from reading a crash dump? If your answer is like mine: NEVER then I say 0 out the file on c: and only have the pagefile on the 2nd drive. There are two more aspects of optimizing the pagefile 1. set the min and max values the same so you don't waste cpu cycles dynamically expanding and contracting the pagefile. 2. right sizing the pagefile. Nothing replaces having sufficent RAM. You do not want to oversize your pagefile. Its a waste of disk space and doesn't add any speed to your system. It can actually slow your system down if heavily utilized since it is a million times slower than RAM. You should start with 1.5x your ram and with performance monitor monitor it. Odds are you can shrink it. I have one old server that has run flawlessly for 7 years and only has a 200meg pagefile.

You will only swap significantly if you don't have enough RAM. Only if the system is swapping consistently will the speed of RAM versus the speed of disk IO be relevant, and then you need more RAM. Nothing to do with the size of the swapfile. If you DO need to swap you need at least enough swapfile space to contain as many pages as are swapped out. If you have a large *underused* swapfile that is fragmented you might see a bit of a slowdown. > > You should start with 1.5x your ram and with performance monitor > monitor it.

But if you have a small amount of RAM (eg 1 - 2 GB) then this only uses 3GB of disk space, which is not worth worrying about. If you have a large amount of RAM (16GB+) you would likely be using only 2 - 3 GB of swap space anyway - assuming you don't run something like an Oracle database. But these are only rules of thumb. Your 200MB swapfile server works for whatever app you run on there, but that configuration would not work in other situations.

Else you may not be able to boot. That "small pagefile on c:" is a good safety measure.
