		S manage swapping between main memory and disk when the main memory is too small to hold all the processes.
		Swapping Swapping consists of bringing in the main memory each process in its entirety, running it for a while, then putting it back on the disk.
		Algorithms to allocate memory for a newly created process (or an existing process being swapped in from disk) when the processes and holes are kept on a list sorted by addresses: S first fit.

	Emuforums.com - View Single Post - crazy disk swapping
		Everytimes i play those games like max payne or return to the castle wolfenstein, i will have a very serious disk swapping problem.
		Mo matter what i do in the games, like walking, shooting, opening door, looking around with the camera,turning left, turning right, etc, i noticed that my hard disk will become very busy, seems like it was doing a very heavy disk swapping.
		I suspect i set the setting to too high until my com cant support,but it seems not true,I have tried to set everything to minimun setting, like 640x480,16bit color, no fsaa, but still cant solve the problem.

	Ch 22 -- Performance Monitoring
		This is the average length of the swap queue during the interval.
		Disk operations are the slowest of all operations that must be completed to enable most programs to complete.
		For example, for a given disk operation to be completed successfully, the disk controller must be directed to access the information from the proper part of the disk.

		This swap file is created as a hidden system file to avoid accidental deletion and will not be visible with a normal DIR command.
		Swapping to a RAM disk will generally be faster than swapping to a hard disk.
		(Disk swapping will not be included as part of the default if the boot drive is A: or B:, because floppy disk swapping is too slow to be useful on most systems.) After 4DOS starts, you can use the SWAPPING command to view the type of swapping in use.

		Generally, swapping to a dedicated partition (raw swap) is somewhat faster than swapping to a local or NFS file.
		However, since the swapping goes through the file system, it is not quite as fast as raw swapping to a dedicated partition.
		The buffer memory caches blocks from the disk, and the blocks that are used frequently stay in the cache.

	MRTG Solaris/Linux/BSD Performance Monitoring Extensions
		Swapping differs from paging in that when paging occurs, only unused portions of a process are sent to disk.
		The purpose of the disk capacity script is to return the used and total disk space on a given file system, through the use of the "df —k" command.
		Disk activity is also monitored by the percentage of time the disk is busy, which indicates when the disk is in use, versus the percentage of time the disk is waiting with transactions in the disk queue.

	F99: CREU Research Group
		Network swapping systems allow individual cluster nodes with over-committed memory to use the idle memory of remote nodes as their backing store, and to swap their pages over the network.
		Network swapping is motivated by two observations: first, network speeds are getting faster more quickly than are disk speeds, and this disparity is likely to grow [3]; second, there is often a significant amount of idle memory space in a cluster that can be used for storing remotely swapped pages [1, 2, 4].
		We tested our system against swapping to disk, mirroring, and the original Nswap algorithm without reliability using three workloads designed to test both cases when disk swapping is expected to perform well and when disk swapping is expected to perform poorly.

	Reviews: After-Market Floppy Disk Drives
		If your ST has only one disk drive then you've experienced the frustration that comes with copying disk files- the constant disk swapping when you want to copy even one file can be maddening.
		After a printer I have found that an external floppy disk drive is the most important peripheral to have.
		I usually don't find this out until I attempt to save something on the disk I thought I formatted, and then get a message that the disk "may be damaged." (PCM is aware of the problem, however and has corrected it.) I experienced no trouble formatting single-sided disks.

		The balloon driver will force the VM to swap which can could potential lower the performance of the VM since it is slower then RAM.
		It increases disk IO since it basically forces the VM to begin to swap via disk.
		The resultant performance impact on the VMs that are forced to swap will likely be benign, however this may vary based on OS and workload.

	Expert Level Unix unx39.htm
		The section "Monitoring Disk Performance Using vmstat" examines how to investigate problems with your disk I/O. If the processes are trying to read/write over NFS, this may be a symptom that the NFS server to which they are attached is down, or that the network itself is hung.
		Disks 30, 53, and 55 are three database disks that are being pounded with updates from the application through the relational database system.
		Perhaps the arrangement of data on the disk is not organized properly (a condition known as fragmentation) or perhaps the organization is fine but the disproportionate access of sd3 (see the blks/s column) is bogging it down in comparison to the other drives.

	2x1GB DDR Memory Roundup: Corsair, Mushkin and OCZ
		They are all the same thing and the fact you cannot escape is that disk swapping depends on snail-pace hard drives, hence why slow down or stutterig occurs in the first place.
		Having said this, a 512MB GPU just might get you out of this disk swapping scenario on some occasion but it's rare, and 2GB of system memory is the only true way of keeping your system away from disk swapping scenarios.
		If you were already close to a disk swapping scenario then the overspill here may just push you over the edge.

		The inordinate amount of disk swapping might be forgivable if it happened only on systems that had the bare minimum specifications.
		But no, this sort of thing (both disk swapping and the rare crash) happened to me on a system that met or exceeded the ‘recommended system requirements’ on every point.
		But, they did, and with the frequent disk swapping and occasional freeze ups for systems that actually meet or exceed minimum or even recommended system requirements, I was forced to knock a bit off in both the gameplay and fun departments.

	How to Run QuickBasic 4.5 on Dual-Floppy System (No Hard Disk)
		When you are prompted for a file not currently in a disk drive, you should use Drive A for all disk swaps.
		This means you need to do extra disk swapping when choosing the Stand-Alone.EXE (BC /O) option on 354K disks (compared to choosing the EXE Requiring BRUN45.EXE option).
		To avoid disk swapping, QuickBasic can be run on high-density disks (such as high-density 3.5-inch floppies, high-density 5.25-inch floppies, or a hard disk).

	Article, Nov95 - Windows 95 too slow? Then Buy More Memory
		Disk swapping occurs when the computer uses the hard drive to temporarily store the excessive memory that an application takes up, often at the cost of speed and system stability.
		In order to minimize the amount of disk swapping, one can buy more physical memory.
		With 16 MB, there is a lot less disk swapping, therefore increased speed.

	PC Card Adapters: Apple and SCM Make PC Card Disk Swapping Easy

		Simple's is a type III card that has an actual rotating disk inside it, while SunDisk uses solid state flash memory and is a type II size.
		Documentation of both PC card disk products and the Apple and SCM adapters were all somewhat lacking: Apple maintains a fax-back service (call 800 462 4396 and ask for document number 10307) with a list of what cards have been tested in its expansion module.

		Since I have an 8088 system and a hard disk and don't have EMS memory, my comments, of course, will emphasize that type of system, but the setup is basically the same for an 80286 system.
		The only real difference is that, with my system, 4DOS swaps itself on and off of the hard disk instead of in and out of EMS memory.
		First, the "/s:dc:\4dos" part is what sets up disk swapping and tells the system to put the disk-swapping file (a hidden file) in the 4DOS directory.

		For example, if Essbase is running too slowly, check the Memory and Disk Swapping groups to see how much free space is available.
		Use this information to determine whether lack of disk space or incompatibility of file system types is affecting Essbase performance.
		For example, if information on the System Info tab indicates that swap space is low, you can use the Disk Drives tab to see which drives have space available.

	LWN: 2.6 swapping behavior
		If application memory is occasionally forced to disk, the unused parts will remain there, and that much physical memory will be freed for more useful contents.
		Without swapping application memory to disk and seeing what gets faulted back in, it is almost impossible to figure out which pages are not really needed.
		But it wouldn't just be program memory getting swapped back in; it would be clever to pull into cache files and directories that get used a lot, so that (for example), your Mozilla cache would be in memory again when you got up.

	replacing a scsi drive with a larger disk -->Re: Swapping a hd in 5.0.6 (Site not responding. Last check: 2007-10-31)
		It's a new disk- it needs fdisk, and divvy and even though Tom is right about SCSI disks not needing badtrk, I run a quick scan anyway because if this disk is a total piece of crap, I want to know it NOW before I waste more time on it.
		However, when you got to the divvy part, it should have been blank.
		If it was NOT blank (which seems to be the implication here) then you either were NOT looking at the proper disk or your system is very very confused.
