Porteus with zstd compression

Here is a place for your projects which are not officially supported by the Porteus Team. For example: your own kernel patched with extra features; desktops not included in the standard ISO like Gnome; base modules that are different than the standard ISO, etc...

APorteus has adopted the zstd compressed XZM module.

Please refer to ArchLinux packages manager for Porteus (Post by neko #75668)

Thanks.

zstd compression instead of xz ... advantage: faster decompression disadvantage: larger module size
So, one might say it would be an advantage for users who have way older hardware and who want to get the most performance out of such machine.
Having larger modules would be an acceptable small disadvantage under these special circumstances, in my book.

But opinions on that might differ. :D
Cheers!

these posts: Porteus with zstd compression (Post by fanthom #72778) ..
"way older hardware" may mean bottlenecks around usb/hd speed, limited amount of ram and cpu freq/cores etc..
also the decompress speed benefit is greater the larger the file/module, not so much for small modules..

And giving you Rava, the other side of the spectrum.

See who the original OP is. The OP built this not reading benifits and limitations of zstd.

He built it because it was asked. Read the whole thread again Rava. And these:
Porteus-5.0-rc1-Openbox with ZST compression
Porteus with zstd compression (Post by raja #72802)

The advantages and/or disadvantages diminishes there itself.
We can be so much experienced. We can have all sorts of explanations as to why zstd is better or worse. But if you just stick to your opinion and do not provide what the community wants, and there is a problem there.

The community asked for a zstd module based porteus, I provide it. Yours and every one else's opinion becomes null and void after that. Dont you think? :)

I fully agree to that.
