Page thrashing Memes

When your working set is larger than your RAM, the OS becomes a sadistic game show host playing "Musical Memory Pages" with your poor application. You're frantically requesting the same pages over and over, and the OS is just yeeting them in and out of RAM like it's training for the Memory Olympics. The result? PAGE IN. EVICT. REPEAT. Your disk is spinning faster than a fidget spinner in 2017, your CPU is crying, and your program that should've taken 5 seconds is now entering its third hour of existence. Welcome to thrashing hell, where performance goes to die and your SSD ages 10 years in 10 minutes. Fun fact: Page thrashing can slow down your system by 100x or more because disk I/O is THOUSANDS of times slower than RAM access. It's like replacing a Ferrari with a horse-drawn carriage and wondering why you're late to work.
