Idea #19382: Decreased performance in LiveCD

bug This idea is a duplicate of Idea #18518: New users tell that Ubuntu is slow (live sessions).
Written by timnwells the 23 Apr 09 at 23:20. Related project: Live CD. Status: New
Rationale
To many people hear about Ubuntu and boot of a live cd to test it, but there is no warning about decreased performance / hardware support etc

Solution #3: Solution #1 but sooner
Written by Ssdg the 29 Apr 09 at 11:25.
My idea would be to tell it on the first screen (the one that offers you to test, install, etc...).

Like:
Try ubuntu without
Install on your hard drive for better performances
...

not by demoting the live CD mode, but by promoting the installation.

I'm not in advertisement, but ubuntu will look much better.

Solution #4: Make user choose when downloading Ubuntu
Written by chareos the 6 May 09 at 14:08.
Make the Ubuntu download to be an EXE file which lets user choose to create a LiveCD (with performance warning here) OR a LiveUSB.

Also, a performance warning on LiveCD boot itself would be great !

Solution #6: Load LiveCD into temporary file
Written by Avantarius the 10 May 09 at 09:42.
For systems with 1 GiB RAM or less, where solution #5 can't be applied, load the content of the CD in a virtual file system which could be located in a file on the computer's harddisk, i.e. create file on a existing ntfs-partition, an unpartitioned space or even use the m$-windows-swapspace.

Solution #7: Put a note into the loading screen
Written by Kver the 16 May 09 at 20:51.
When a live cd shows the loading bar, there's plenty of time for a message such as "Loading and running content from this DVD will result in slow performance, and changes or customizations will not be saved."

Paragraphs #2 and #3 of the rationale should actually be in solution #1. Please separate the rationale and solution so other Brainstormers can contribute.

#5 : does not offer a solution for everybody. And what f in live session user starts a memory-hungry application ? any malfunction in a test live session would be a showstopper, keeping the user to really install ubuntu.

solution #5 is irrational. The system is already loaded into ram. Loading the disk also into ram is redundant. If you have plenty of ram, all the files on the disk will be cached anyway.

@chareos: I think #6 could be a good workaround for this. And for the outrunning mem problem you could do the same thing for using it as swapspace.

@danbhfive: Only things currently in use are loaded into RAM to make the CD boot quicker. Every program you start must be loaded from the CD, you have even to wait for the icons to load, the first time you open the main menu ;-)

The thing i ask is to load EVERYTHING into RAM before using the system (like i.e. PuppyLinux does). Of course boot time might be 3 minutes longer, but then you could experience an incredibly fast system!

#6:

Don't touch the hard-disk!!!
A lot of people use the live-CD for partitioning.
There was a big Problem in former releases,
when gparted had to unmount the swap-partition
and the result was a big crash!

Further on the comment,
that the hard-disk will stay untouched,
is the only reason why people try the live-CD.

Voting down #5.

Even if we can assume the user will not use up all their RAM, the system would be too quick. It would give users an unrealistic impression of the responsiveness of the final system.

Puppy and DSL can get away with it because they're freaking small. The final system is meant to sit entirely in RAM, when possible. Ubuntu is not.

A warning that the LiveCD will run slower is a great idea. I recall a disgruntled YouTube user complaining about Linux. He said it was slow, it took five minutes to boot, and ages to start applications. I couldn't help but laugh at the poor guy.

The solution for #6 can be found in the install program, located on the live CD.
