Just this involves reading its block(s) from disk into a read buffer and then transferring it bytewise into the program memory before execution. Some OSes optimized this by not swapping out code segments, but reloading them from its (EXE) file. Except, taking cache memory from main memory may decrease performance, in tight memory situations, by having less memory for programs, resulting in programs being purged which could have resided happily in main memory without a cache taking up room. Like all disk operations this can be sped up by a disk cache. That's a costly (and slow) disk operation, every time a code segment gets purged. Effectively switching from use of classic paging (for program files) to memory mapped (code) files.Īt that point some history/theory of operating systems, program loading and virtual memory might be helpful:Ī classic program load means loading the code portion(s) from disk, execute them and if there's a shortage of memory, the least needed code gets moved out into a paging file, to be reloaded when needed again. It allows to map a cache page into program memory. The workings are based on the improved (disk) cache handling of Win98 offering the MapCache feature. WINALIGN.EXE can be used for a general optimization. WALIGN.EXE is distributed with the system install but looks only out for (older) MS programs which are not aligned. Winalign.exe is included in the Windows 98 Resource Kit to optimize other programs. Walign.exe is included in Windows 98 for automatically optimizing Microsoft Office programs. This allows the Windows 98 MapCache feature to map directly to sections in cache. WinAlign aligns binary sections along 4 KB boundaries, aligning the executable sections with the memory pages. WinAlign (Walign.exe and Winalign.exe) are tools designed to optimize the performance of executable code (binaries). This results in more memory being available to run applications, and lesser usage of the swap file. On the FAT32 file system, Windows 98 has a performance feature called MapCache that can run applications from the disk cache itself if the code pages of executable files are aligned/mapped on 4K boundaries, instead of copying them to virtual memory. Wiki, BTW, also notes this under Performance Improvements in the Win98 entry: This can result in significant performance increases by freeing memory. By aligning files in this manner, the Windows 98 CacheMap feature can map directly to sections in the cache memory. ![]() The new section table is then updated with this information, and the file headers are also updated to denote the file is now aligned to a 4-KB boundary. Winalign.exe and Walign.exe (*2) optimize programs by rewriting a program's file headers, creating a new section table, and then writing file sections, each of which starts on a 4-kilobyte (KB) boundary. Some information could be found back then at Microsoft's Knowledge Base (*1): ![]() And if you are accustom to listening to your favorite music while doing your work, no worries, the wallpapers is designed to allow you to independently mute the wallpaper sounds with one click so that you can enjoy the music with the wallpaper running or vise-versa! And it is even better yet! To maximize your view the wallpaper also allows you to hide all desktop icons with one click, except the project that you are currently working on.At that point, Setup executes WALIGN.EXE. The animated wallpapers breathe new life into your computer and let you enjoy your favorite, pristine, and relax scenes-live while you are doing your work. Unlike screensavers, the animated wallpapers are designed to run behind desktop icons and on top of tradition boring static desktop image or background on your screen. Or have your favorite under the tropical ocean scene screen savers which only runs when your computer is at idle state for a few minutes and you are not there to enjoy. An under the tropical ocean scene which normally you have to scuba dive to see, or have a pricey and labor intensive maintenance salt water fish tank in your home. Virtual Aquarium wallpape features Regal Blue Tang (Dory), Yelow Tang, Purple Tang, Moorish Idol (Gill), Black Clown, Orange Clown, Green Clown, Pink Clown in crystal clear water under the tropical ocean and coral reefs, full of sea Anemone, Soft colorful corals, and hard coral, polyp, sea crabs, octopus, and Fire shrimps with crashing wave of ocean sounds and under the sea volcano.
