Comment Cache is not always good (Score 1) 381

I have run into situations regularly where caching is too slow, or a bad idea. Take a backup application for example. The backup applications task is to enumerate the files and copy the file data to the destination location. To use the cache for this imposes a performance hit on other processes in the system, and slows down the IO path. Why waste cache on data that will NOT be accessed again? Why have the memory copy instructions when not needed?

Filesystems are designed to abstract file handling. Applications need not know if the FS is Etx4, Xfs, Btrfs, etc. They all have a standard POSIX interface to manipulate files. If this were not the case, we'd live in utter chaos. So that was a bogus point. As for apps like Photoshop, we already have better Linux equivalents; InkScape and GIMP for example. High-level applications like Dropbox need not worry about the FS, and should not worry about distribution so much. There are many development platforms that can help build distribution and platform agnostic applications. Take Microsoft Visual Code for example. And if the application has a web interface, then the OS and distribution make no difference. I can access my Google Drive with any web browser, or via apps. Google Drive has a native app for Windows, but not for Linux. However, I use my web browser to access my files in Drive under Linux every day. For Dropbox to drop Linux application support is really not such a big deal. There are already open source clients that can access Dropbox in Linux. From Dropboxes perspective, why not let the open source community create the applications?
