This post gives this command to resize swap
sudo dd if=/dev/zero of=/swapfile bs=1G count=8
Does the blocksize (bs) value in swap settings matter? If yes, is there a command to show current settings about swap block size?
If swap block size really affect something, I would like to know what it would be before I modify the settings.
If not, please explain a little bit why swap block size would not actually affect the performance of swap.
Some additional reference would be better.
