I recently downloaded the 13.1 update (KDE-LIVE) stuck it on a usb stick and booted up. The boot up process was fine but slow. Going into the DE was extreemly slow. I am running 12.3 on my laptop right now with no issues. But everything I tried in the Live version was just extreemly laggy on my system.
HP Pavilion dv6 with 6gigs of RAM.
I’ve thought that it could be the usb drive itself and will try another drive when I get the chance. Anyone else having issue’s with lag in the 13.1 distro? Mind you I haven’t installed it do to it being so laggy. Not sure if that would make a difference either.
Anyway does anyone have anything they think I could do to make things faster?
More likely you should check running processes using ‘top’ in a terminal and make sure something isn’t running at 100%
Or perhaps, it could easily be your GPU? Whatever that is and you are running in some crappy graphics mode
Windows 8 users should make sure windows 8 is really shutdown !
Weird. I have an 8GB USB stick I use for live images only. 13.1 images run like mud. Gave it’s identical sister a try, resulting in a smooth experience. Try other ports, make sure the stick in 100% OK. Perform media check.
[SUB]after installing it to a test drive (USB-320g) It seems to be running fairly smooth.[/SUB] I guess that hybrid has caused the Lag on the usb thumb drive. I did switch thumb drives and it was still very laggy. I guess I could try the kiwi_hybridpersistent=no thing but after installing it there really is no need to mess with it. I’m currently running openSUSE 12.3 as my daily driver. I probably will switch over to 13.1 after I finish testing things out and make sure its working with all my hardware. I’m looking at upgrading the 12.3 after the first of the year. I will be moving here soon and will do all that work after the move.
So what makes this kiwi_hybridpersistent so slow? This would be extremely painful if it was being used to rescue a system something I do with Live distro’s At moment still glad I have 12.3 on a thumb drive.
[size=2]The hybrid partition is only used when running from the live USB stick.

Based on my own observations, it seems that:
When the live USB stick is ran for the first time with the default kiwi_hybridpersistent=yes, it first formats any remaining free space on the USB stick as a ext3 partition labelled hybrid.
It then creates the directory structure shown here:[/size][size=2]SUSE Paste
This is then used for the ‘persistent’ data between boots from the USB stick. The read/write to the hybrid partition is, I assume, causing the slowness. I would note that I was using USB 2.0 perhaps with USB 3 it would be acceptably?

Likewise, I keep a live version on USB stick. Booting from that with the kiwi…=no option enables it to behave as with 12.3, however, it keeps on issuing low disk space warnings…
Not too sure if I want to resurrect this… But I’m very curious… What spec PC is that running on? USB stick V2 or V3?
I did some timings with 13.1 RC2 and found that booting from a live USB stick with persistence enabled was painfully slow.
Using a modest spec PC (Athlon 64 X2 5600 using USB 2.0), timing from the start of kernel loading to the plasma desktop having fully loaded.
13.1 RC2 KDE Live USB with persistence – 329 seconds – system very slow. Dolphin for example taking almost 17 seconds to open. So sluggish as to not really be practical to use.
Still getting almost identical timings with the 13.1 release version.

Of course it has to be slower that a hard disk install on the same machine. First, it runs off a usb
stick, which is by definition, slow (because it is usb, and because it is flash). Then it runs with
settings similar to a failsafe boot. It has to use a video mode that runs on every machine, without
access to proprietary drivers, maybe even vesa. Then it has to do autodetection, it can not rely on
configured settings.
So I don’t expect much. It works and you can test things.
However, if you can demonstrate that 13.1 on usb in the same machine and stick brand and model is
slower than 12.3, well report it in Bugzilla. However, the persistent filesystem did not work in
12.3, so that’s a factor.

I am able to demonstrate that - but - it is not a valid comparison unless I boot with the “kiwi_hybridpersistent=no” on the 13.1 version. In which case, it is still slower, but not sufficiently slow to warrant complaint, and nowhere near as slow as when persistence is enabled.
This is not a bug, initially I was unaware of the hybrid partition being created and used by default (with 13.1), therefore my comparison of 12.3 (no persistence) against 13.1 (with persistence) was invalid.

Still, the system with persistence should not be that slow. Mine is not. I did not try the gnome or
kde live system, I tried the XFCE rescue image. I actually find persistence very useful.
The system would be noticeably slower if it is writing too often and/or that particular stick is
very slow when writing (some are). Stick manufacturers do not clearly specify the write speed.

OK. Let’s try to get these comparisons as like for like - I’ve downloaded “openSUSE-13.1-Rescue-CD-x86_64.iso” which I’ve placed on the USB2 stick that previously held “openSUSE-13.1-KDE-Live-x86_64.iso”.
Booting (with default persistence) into the XFCE desktop takes 124 seconds from start of kernel loading to working desktop. No lag, perfectly usable. A vast improvement over the 329 seconds and not really usable, that I was seeing with the KDE Live version.
I know that XFCE is lightweight compared to KDE, but the difference in times is quite amazing.
Thank you very much for introducing me to XFCE! - I shall keep the rescue image rather than the KDE live…
It would be interesting to see what times you achieve when running the KDE live version on you hardware/stick combination. (I appreciate of course that you may not have the time, or desire, to do that.)

I guess it’s simply down to the amount of data that is being read/written when using KDE. The USB stick I was using is a Corsair Voyager 8Gb USB2 quoted speed is 33 MB/s read 16 MB/s write. I’ve measured it (approx) as 29 and 14… which is not blazingly fast by any means…
I can’t say for previous versions, but 13.1 has. First boot from the USB stick creates the ‘hybrid’ partition, which is used for persistent settings. I made a few changes to the XFCE desktop and those ‘persisted’.
I will attempt to clarify my earlier comments.
