Hello folks,

I'm an absolute beginner in data compression. I was wondering an efficient way to compress the RAM contents.
I have used ZSTD from Yann Collet's github (thanks Yann for the great work) but it is slower than LZ4 algorithm currently.

I have following questions

1. What is the best option for compressing RAM contents? Any specialized encoders? (open source will be great)
2. Can I use integer compressing codecs to do the job on RAM data? Are they similar?
3. Can anyone point me to the starting point for learning data compression? (Prerequisites etc.)

Thank you sincerely.
