Without installing OS 12.1, any way to know if it'll run faster/slower than 11.3 on my machine?

I currently have openSUSE 11.3 running on my machine and it runs really well, but I’m interested in possibly updating to 12.1. What I’m afraid of is that it will be too much for my machine and not run as well as 11.3. Aside from actually installing it, is there any way to know how 12.1 will run on this machine?

current system/setup:

CPU: AMD Sempron™ Processor 3100+, 1,808.35 MHz
RAM: 1.4 GiB
Free memory: 95.5 MiB (+ 625.6 MiB Caches)
Free swap: 2.0 GiB

**OS: **openSUSE 11.3 (i586)
Desktop: KDE 4.4.4 “release 3”

Display: nVidia Corporation
Model: GeForce 8400 GS
2D driver: nvidia
3D driver: NVIDIA 275.21

(500GB hard drive)

You could boot from the KDE live CD, and see how that runs.

With history as our guide…newer OS’ (in their default configuration) tend
to be slower on the same hardware. I believe the assumption is that newer
OS’ will be installed on newer hardware that can take advantage of the gee
whiz latest features. However, that doesn’t mean you can’t make the newer
OS perform as well as the older version, you just may need to tweak it a
bit.

is that different than live usb? in live usb, it’s pretty slow because it has to keep “consulting” the usb stick, is this not the case for live cd?

Actually you should find a live usb much quicker than a cd

Partition your HD and do a real install, it’s so easy!

LiveCD will be considerably slower than installed system, for obvious reasons. The comparison may have some value (or maybe not) if you compare LiveCDs of both versions. Even so the systems will have considerable differences from the installed one, that might lead to erroneous conclusions. The open-source video drivers in the liveCDs, for instance, might give poorer performance, depending on what video card you have.

I always found an incremental new version faster/better than the previous, due to better drivers, optimizations and such, exception made on big desktop changes like KDE 3 to 4.

Also note that your current system probably have optimizations you made long ago and hardly remember, most of which you’ll end up doing again in time.

So, considering that in a few more (six ?) months 11.3 will be discontinued, it’s not a bad idea to upgrade a couple of months AFTER 12.1 is released, when most remaining bugs will be solved and the less popular packages will be available. Unless you want to participate in the bug squashing, never a good idea in productions systems. So, in short: upgrade, but not now.

Another option, if you 20 or so GB available in the last partition of your disk, you can repartition it, install 12.1 (using it’s grub setup to multiboot) and test it to your heart’s content. If you’re unhappy with 12.1 you can easily revert to the previous status quo.

As others have said, the CD is the slowest, and install on a hard disk is fastest.

Run from a live CD or live USB to test whether it is stable on your system. But don’t expect that to be a good indication of speed.

The speed of 12.1, if installed on your hard disk, should not be much different from the speed of the 11.3 that you currently use. Well, okay, the startup time might be different. But once past the startup, the speed of continuing operations should be similar.

I seem to recall that with 11.3, the default was that desktop effects were off unless you turned them on. With 12.1, they are on unless you turn them off. If desktop effects are not important, then try turning them off. The newer versions of KDE (4.7.2 with opensuse 12.1) are more stable than the version 4.4.4 that you are using.

This doesn’t always happen when memory is scarce, because newer versions
often have bigger programs and libraries.

The 1.4 GB the OP has can be the show stopper for newer kde versions, it
maybe possible to tweak it for lower memory consumption, but looking at
the machine where I write this (11.4 with kde 4.7.3) I have right now
1014 MB memory consumption by the applications (means without
cache/buffers) and run only thunderbird and firefox in this moment.

It’s nothing like six months :frowning: That was back in the good old days :slight_smile: If
I remember the policy correctly, it goes obsolete two months after the
12.1 release. So wait a month by all means (that’s what I plan to do),
but two is pushing your luck.

I have 697MB consumption with the same programms open…so don’t know how comparable this is.

Probably not very since we don’t know the plugins running under Firefox, how
long the apps have been open (usually memory leaks) etc…

what kind of tweaking are you referring to? i’m not exactly an expert with OS tweaking, and configurations.

I actually have 170GB avail on my home partition. Can you explain how I’d go about:

1, installing 12.1 on there
2. how i’d remove it without affecting my 11.3 install

Please post the output of

question: what’s that /dev/sdb1?

You tell us what sdb1 is
You have 2 HD’s

A. 320GB
B. 160GB

To do it on sda
Shrink some space off sda3
Create an extended partition in the freed up space
create a ext4 partition in the extended space (Or 2 partitions if you want to separate /home)
Install 12.1 in there

Thanks. How would I do that? What program do I use? And how would I undo that as well?

This video may give you some idea. But it’s not a representation of exactly what I mean for you, but it shows the resize process

You undo it with the same tool.

I agree. Same holds for my machine. I seldom get over 1.1GB RAM consumption - mostly 0.8-1.0 - and my machine’s been running now for 4 Days straight (a small radiator for my room) with TOR, BOINC and Firefox.

Though I have to say, that FF7 looses in speed with progressing time.

BTT:
I’d just squeeze some 10GB of HDD Space off somewhere and install the new system there for comparison.
IMO the YaST Partition Tool is pretty comfortable for this task.
