Because it consumes the most amount of power it’s also more appropriate for desktops.
You are almost always better off on a laptop using the Balanced or Power saver plans, but High performance can make Windows faster by trading battery endurance for power. Sometimes manufacturers also include custom plans here. The three defaults are Balanced, High performance, and Power saver. In case of virtual file system it might appear that working with container file on the disk will give you satisfactory results (as virtual file system usually has a memory cache) and you won't need to keep in-memory copy at all.Windows has three default settings for how your processor ramps up its frequency. With SolFS or other virtual file system you can have a copy of the storage on the disk as well.
But this will require modifying sample RAMDisk driver (and this involves quite a lot of kernel-mode programming). I see no obstacles for the driver to have a copy in memory and perform writes to disk asynchronously when needed. Our Callback File System or CallbackDisk products (see virtual storage line) are an alternative, however, as I mentioned in the first paragraph, they won't solve your problem due to user-mode context switch. MMFs tend to be faster for most file operations, that's why they are frequently mentioned. No, memory-mapped files (MMF) are literally files on the disk (including a virtual disk if you have one), which can be accessed not via filesystem API but directly using in-memory operations. SolFS seems to fit your task nicely so if you think so too, you can contact me privately (see my profile) for assistance. Our SolFS (Application Edition) is one of such products that you can use (I can also remember CodeBase File System, but they don't seem to provide an evaluation version). If all you need is a handy management of bunch of files in memory using Stream class (with possibility to flush all of this to the disk), then you can make use of one of virtual file systems. Why kernel mode? Cause as you could see with Dokan, switching back to user mode to store the data causes major slowdown. Driver development, though, is tricky, and if something goes wrong with the sample or you need to extend it, you would need to dig deep into kernel-mode development (or hire someone to do the job). Windows Driver Kit includes a sample driver, which (coincidence?) has the name "RamDisk". via filesystem API functions and classes), and you want it fast, then (as I suggested in reply to your previous question) you'd need to create a RAMDisk driver. If you need to work with file system (i.e. There are several approaches that depend on specifics of your task. creating a virtual drive which I can create a symbolic link to? Such as G:\Data_Files\?Īre there any other alternatives to Dokan/ImDisk with a. My approach currently is to Create RAMDisk, Create Symbolic Link between Data Folder for Game Server and the RAMDisk, then launch the Game Server process.Ĭan Memory-Mapped Files function the same way, I.E. It was mentioned to me previously to try Memory-Mapped Files. NET API, i'm looking into alternatives now.
Since these are the only 2 Filesystem Drivers I know of that have a.
Dokan was considerably slower than the average Hard-Drive, and I was unable to get ImDisk to function properly. In a recent attempt, I tried to use Dokan/ImDisk to create a RAMDisk programatically for the Server Application. For the game Minecraft, the general approach when running the server application is to run it in a RAMDisk, as it is uses hundreds of tiny files for world generation, and the I/O speeds are the major bottleneck.
