Hi everybody! Since an increasing number of users has hyper-threaded CPUs, it would be a good idea to include a SMP kernel for the 1CD install (just heard it is not there, no time+bandwidth to test myself). Otherwise, you will probably have significantly lower performance with this type of CPU. Since there is little space on only one iso, I suggest that we ship a SMP-enabled kernel for everybody. This should not decrease performance for uniprocessor machines but get you full speed on hyperthreaded CPUS. Question: Is this going to break anything? I'm thinking especially of binary-only drivers that might not like SMP systems. Or maybe other problems when you run an SMP enabled kernel on a system with just 1 CPU. Cheers nordi

Sure it does decrease performance on UP systems. It's just a question whether the loss does justify shipping an extra kernel. But to decide this you should do benchmarks about how much performance is lost. On hyper-thread processors it is even a question whether the performance loss by using an SMP kernel outweighs the speed gain by activating hyper-threading. Actually I don't know the answer about this question because I never meassured it and it is most likely dependant of your system usage pattern.

As I said, not my system. Just read in a forum that the super-openSUSE-RC1-20050909-standard-gnome.iso doesn't have it. I will ask the poster if/how he checked that. Cheers nordi

I have cc'ed magnus ........ Andreas
In the process of updating the ISO right now. Should be on Andreas server tomorrow. Andreas, should the SMP kernel rpm be in My.sel or will it be selected automatically if SMP is detected? Cheers, Magnus

good question well presented .... dunno the answer though ;) My dual CPU machine I have here cannot be reinstalled unfortunately since I have a large LVM set on it ..... Can someone on here try the kde iso out on a dual cpu system and get back to us? Or maybe someone from SUSE has the answer? Andreas

I have SUPER (with kde) installed. Both processors were detected and smp-kernel was selected automatically. Jukka
Guys, When I hit ENTER at the GRUB screen, it takes 15- 20 seconds to load/analyze/mount my disk drives. I have the same issue with both my LAB server (DELL PowerEdge with SATA drives) and my laptop. How can I optimize this? How is it possible to boot KDE in 7 seconds (or 11 with the standard OSS build). I've tried to create a small boot partition with different file systems etc but to no avail. No mather what I do, it always takes a long time for this initial step. Any advice/tips/trix is appreciated. Cheers, Magnus

Make sure your IDE disk configuration in the BIOS is correct and non-existant disks are disabled. Ciao, Marcus

Marcus, The disks are configured correctly in BIOS and no 'non-existant' disks are in there... Is there anything else that can be done, such as choosing ext2 instead of ext3/reiser etc for the boot partition, only having 20mb for the /boot etc? Cheers, Magnus

So that means the SMP kernel was not included on the Gnome CD, but now it is? Btw, will you also provide delta-isos for the 1CD isos? Since these change quite frequently I can imagine people don't want to download hundreds of MB every week. Or does makedeltaiso need too much RAM for normal systems? Cheers nordi
The SMP kernel wasn't provided on the first CD but it will be from now on. I will also make delta iso's available. My issue at the moment is that even though I have both the default and the SMP kernel on the ISO, it installs the default on my machine (I only have hyper threading but I think the SMP is suppose to be selected on HT machines). As soon as I solved that (and any suggestions are appreciated), I will upload the ISO and delta to Andreas server. Cheers, Magnus
