AI-generated summary
The text discusses configuring zram on machines with low memory and slow disk speeds. It highlights the significant performance improvement of zram over traditional disk swap. The steps include installing zram-tools, stopping zramswap, editing the configuration file to set the compression algorithm to zstd, allocating 50% of memory for zram, and starting zramswap. This setup enables high compression rates, resulting in much faster swap performance compared to using pure disk swap.

Suitable for machines with low memory and slow disk speed
The speed increase is very noticeable in practice, much better than pure disk swap performance

apt install zram-tools
zramswap stop
nano /etc/default/zramswap

Modify and remove the # at the beginning of the line
ALGO=zstd
PERCENT=50
PRIORITY=100

zramswap start

The configuration of zram is now complete
It enables a high compression ratio for half of the memory, significantly faster than pure disk swap
