Experiment around with settings that you think may help you. The After Effects preferences you utilize will be up to, well, your personal preferences! We can’t recommend anything specific because it really does depend on the user and the user’s machine. If you also want to restore the default keyboard shortcuts while you’re at it, you can Alt+Click (Windows) or Option+Click (Mac OS) the ‘OK’ button. Adobe makes it a little more difficult than that. This is not very intuitive, since you may expect there to be a button to reset your preferences, in the actual preferences menu. While After Effects is starting up, press Ctrl+Alt+Shift (Windows) or Command+Option+Shift (Mac OS), and your preferences will be reset. Resetting preferences is easy, but will require good timing. But there are so many different settings to adjust, that setting everything back to normal may just be the easiest.
If something has gone wrong, the After Effects preferences is one of the first places you can look for issues. dentry is common across all file systems, but inodecache. dentry and inodecache are memory held after reading directory/file attributes, such as open() and stat(). This will most likely be for troubleshooting. Linux kernel prefers to keep unused page cache assuming files being read once will most likely to be read again in the near future, hence avoiding the performance impact on disk IO.
For a variety of reasons, you may find yourself in need of resetting these preferences back to the original.
So you’ve adjusted all of your preferences to be exactly what you need.
