Partition recommendation for multi-boot and benchmarks.

[C1REX]

Apologies for a noob question but I'm back after 14years break :)

I want to prepare my system to have Gentoo, Windows, Clear Linux and two other distros.
One of the goals is to play with optimisation for best benchmark scores and to beat Clear Linux.

I've got 1TB nvme and 32GB Ram.
My idea was to have small boot partition for GRUB, SWAP (how much?), 100GB for each system and all the rest for /home.


Does it make sense?

Thank you.

ClearLinux goal is "By default, Clear Linux OS prioritizes maximum CPU performance with the philosophy that the faster the program finishes execution, the faster the CPU can return to a low energy idle state"
No need to test anything, anyone compiling with gcc is awful for any energy saving goal ; and gcc is heart of gentoo

ClearLinux use systemd
I wonder how much pain it would be running it without systemd, while on gentoo, it's a cake ; which made me think i cannot live without gentoo

And your own personal goal: beat ClearLinux speed, you might do that in gentoo, but at end, you would not proof any gentoo superiority over clearlinux, you would had just prove "you" have succeed in optimizing something better than clearlinux ; and i suppose (never tried it) it's something "you" might be able to do in clearlinux too.

So no, it doesn't really make sense to me

C1REX,

Have a common /boot and or EFI partition or you will go mad.
Unless you want to hibernate, have a common swap too. With a common swap and hibernate in use, you cannot start a different OS without destroying the hibernate image.

A common home can work if you have different normal usernames on each install.
The problem to avoid here is different distros installing different version of the same packages having incompatible per user settings in /home/<username>/

/tmp is shared and goes into a tmpfs.

which benchmarks are you talking about?

[C1REX]

Phoronix Benchmark where amd cpus do way better on linux than on windows. Also clear linux leads the way in performance.


Here is one of many examples of such benchmarks

I've learnt about them from non linux pc communities. It got me excited and made me back to linux after long break.

Thank you for the tip.

So my plan is to do something like this:


/dev/sda1 BIOS boot partition. (2M?)
/dev/sda2 Boot partition. (128M of ext2?)
/dev/sda3 Swap partition (is it still twice of my RAM? it would be 64GB then)
/dev/sda4 Gentoo (200G)
/dev/sda5 Windows (300G)
/dev/sda6 Clear Linux (100G)
/dev/sda7 Ubuntu (100G)
/dev/sda8 Other Linux distro (50G)
/dev/sda9 Other Linux distro 2 (50G)

It's not exactly 1TB here. I will create all that using one of those easy distros with graphical partitioners and just decide moving sliders how much to allocate to Gentoo and Windows.

Follow up.

I don't know what to do with Windows.
It tries to create 4 partitions (boot, recover, system and default - the biggest).


Do I need all 4?
