This article is just some guy who thinks he has enough knowledge and assumed that what he did improved his system performance because he probably perceived a difference that wasn't actually there. Kind of like people who defrag their windows partition on their PC, and even though it's no faster than before, it feels good that they did it. It's a psychological thing.

Generally, I wouldn't follow the advice of any random writer on the internet. I'd want it to come from a reputable source who understands the ins and outs of what's going on, and can relay the pros and cons to the reader, or the system provider itself(in this case Sony).

It's rare that Sony will tell you to rebuild your databases to "fix" things. If you read their forums, they tend to have you try other things first. Even when it does it automatically after like say a power failure, it doesn't actually do anything if it doesn't find a problem, or only fixes a problem that arises. It doesn't rebuild the entire database like a manual rebuild does.

Back in the day (PS2 GameCube era) it wasn't a issue as most data was store on your CD disks. Once hdd became standard hardware inside, (ps3 xb360) it became standard for consoles

This is actually something you shouldn't do manually unless instructed to do so by Sony, or it's a last resort trying to fix other problems. Sluggish OS's are generally just a perception thing with the PS. I doubt actual performance was increased with this, because the main OS screen to get to other things doesn't get changed enough to actually bog it down. It certainly wouldn't have an affect on apps or games since they run in their own hypervisor, so as long as the files involved aren't corrupted, it will run as it should. Typically performance problems there have nothing to do with fragmentation, and a simple uninstall/reinstall of the affected program will work fine.

Again, not true at all, as the ZFS and UFS do not need to be defragmented. THESE ARE FACTS OF THE BSD OPERATING SYSTEM!!

It does other things. It repairs file pointers attached to the OS, restructures the file index to basically defrag that and remove bad pointers and update anything that is "defraged", and can reset certain parts of the system OS to "fix" problems that may not exist. It also does other things but they're kind of technical.

For the most part, there is no reason to do this with UFS. It is pretty efficient at putting files on the disk in sequential order. Pointers to non-existent files aren't a problem on a relatively small file index like you'd see in consoles where most files are actually packaged into bigger files. Resetting the OS to some degree actually causes unwanted outcomes....such as the user above who says it removes their organization of games into folders. Doing this on larger more diverse file systems like you'd see in a general purpose PC can be beneficial, but there is another function to handle this in FreeBDS/Linux

I wouldn't recommend doing this unless instructed to by Sony or a qualified repair technician, or as a last resort to fix other problems you may be having.

Sometimes the system will say it's rebuilding your database after a power failure or botched install, but that is a simpler form of the feature which only repairs the "broken" files that it thinks exists. It will analyze everything, and I believe it does remove pointers to non-existent files, but it doesn't actually defrag anything or reset the OS. That's why it goes pretty fast, and seems to skip over large sections in the progress meter.

Generally, if you're having a problem with a particular game or app, simply deleting it and reinstalling will fix it.

If your hard disk is close to capacity you may find that you have disk performance (HDD) issues. A rule of thumb for hard disk drives is to try and restrict your data storage to about 85% of your HDD's capacity.

Usually, for home use, it is rare that you will need to defragment your hard disk although for enterprise systems defragmentation is only required when needed and there are plenty of tools that will give the System Administrator warnings that a defragmentation is required so appropriate change requests can be raised.

Nine Souls does now.

Why did you have to remind me of that ending!? I thought I bleached it from my memory.

Or maybe a game of cat and mouse if they're so fixated on his death. This guy single-handedly killed half of the Fireflies. He's a wanted man. They find out where he is and start hunting him down. Ellie hates him now, but he doesn't want to get her into this mess so he leaves Tommy and the little happy town to not cause them trouble. Trouble comes knocking anyway. You play as both Joel trying to lay low and evade his hunters and Ellie setting out trying to find him. He either dies mid-way fighting for his life or meets up with Ellie, they make up, get in a tight situation where he defends her and still die.

Too much cheese, not enough shock, though.
