Perhaps we should choose something else to be the selling point of it when we advertise Haiku to other people. Because this statement is, simply wrong.
Linux is lightweight, but Haiku is not! Let’s compare.
A frestly installed Haiku 64 bit used around 250 MB of RAM. Yeah, it’s pretty low. But a freshly installed Debian Linux from the text installer without X only consumed around 93 MB! Then if we add X and a lightweight WM it’s still much lower than the number 250 MB of Haiku! Don’t underestimate X11’s WM, they are very powerful. With a suitable customization, they could provide almost if the same level of features of the Haiku’s WM.
Also keep in mind Windows XP, a freshly installed system, only consumed about 98 MB to 128 MB of RAM! This is what the word lightweight really means!
Yeah, I know XP is 32 bit. But 32 bit Haiku used almost the same 250 MB as of 64 bit!
Haiku, when at it fullest potential, e.g: proper graphics acceleration, fully themed and decorated,… will be something as heavy weight as MacOS. I don’t know if we could reach this state or not, but let’s hope, then I could used a MacOS like OS with Mac like experience without anything Apple! That’s great!
Disclaimer: I don’t know if you are officially advertised Haiku is lightweight or not. But I found some blogs and tech sites on the net said so. If it’s not the case, please don’t blame me.
