There are various reasons that can cause google chrome high CPU usage, 100% disk or memory usages. Such as Virus malware infection, malicious Chrome extensions, poorly designed extensions, or the Browser itself get corrupted/outdated etc that causes Google Chrome to use up too much CPU or memory on your System. Swappiness can have a value of between 0 and 100. Swappiness=0 tells the kernel to avoid swapping processes out of physical memory for as long as possible. Swappiness=100 tells the kernel to aggressively swap processes out of physical memory and move them to swap cache.

It's not normal, but it can happen depending upon what you are or were doing. According to the kernel documentation for the proc filesystem, 'buffers' is the amount of memory used by cached raw disk data as opposed to 'cached' which is the memory used by cached file data.
Buffers should normally be much smaller than Cached, but you can make buffers shoot up if you perform a lot of direct disk IO. I was able to make mine increase significantly by running
sudo dd if=/dev/sda of=/dev/null bs=1M count=16384
. Here are my results.Do you have any programs performing a lot of block IO?
