That satisfying drop in memory usage was costing me speed.

How does one go about limiting the amount of memory Linux will use for cached memory? I'd like to see if it's the cause of an application crash. You can't, readily, and I don't see how it could be the ...

If you're having PC memory issues, you might assume clearing your RAM's cache might sound like it'll make your PC run faster. But be careful, because it can actually slow it down and is unlikely to ...

I have a database VM running on RHEL 6. It's configured for a large amount of RAM: 160 GB. However, 99% of the time, well over 120 GB is listed under "cached" (as viewed with "free -g"). I was always ...

When I was diagnosing a friend's PC that was struggling with constant slowdowns, Task Manager showed RAM usage sitting at 95%, but no single process was using a large amount of memory. We tried the ...

Why it matters: A RAM drive is traditionally conceived as a block of volatile memory "formatted" to be used as a secondary storage disk drive. RAM disks are extremely fast compared to HDDs or even ...

A processor cache is an area of high-speed memory that stores information near the processor. This helps make the processing of common instructions efficient and therefore speeds up computation time.
