Charlie Heck charlie , I have 512 MB of RAM and mine often needs it, especially on those big number crunching jobs like analogue to digital sound creation, dvd to divx creation, you need all your system has then. John Haven't got DVD so cannot comment on that score. Bringing up 2 MB graphics does jump the memory meter a lot especially if I have a few programs open at the same time, but it still leaves my swap 99% free. Yet on my other system, which has 256 MB RAM and 296 MB swap the memory jumps up real quick, but renders the graphic faster than the 512 MB RAM machine and leaves my swap 99% free. Don't know why that happens. But if I open a 7.9 MB graphic, that leaves me only 76% swap on the 256 MB RAM system. So if your working with large graphics like this, I suppose you would need more swap. Charlie You certainly do, not only graphics, but sound manipulation programmes as well. Take rezound for instance when caching up analogue audio , it is actually loaded into memory first, not on the harddrive, not only that, but in it's rezound file state if adds about the same amount of data again as the original analogue converted to .wav file original. So if you have a 512 MB DDR ram stick it quickly fills that and some, and in that sort of situation you despirately need /swap space, so much so that it pays you to split the conversion in half in order to load less into memory in one go. Nevertheless rezound does a good job with the resulting converted files. But I notice quite often you get worbled sound during rezound playback, I think due to the rate in which .wav audio streem has to be retieved by rezound from /swap as well as memory. Any sound stream that must be retrieved from /swap is subject to data flow across the HD to memory and the availability of the programme that governs data flow to operate in a restricted memory situation where other programme use is crowding out I have to say none of this actually affects the finished files, they work fine in each relevant programme that uses them, it's just that programmes like rezound when called upon to work with maybe 30 minutes or more of audio data needs a lot of memory and that a /swap partition is vital.

[newbie] Forgot the swap partition...
Hi all, As I installed mdk 9.2 on a brand new desktop, I totally forgot to make a swap partition. The installer didn't complain and everything looks fine now, but I'm still wondering if it might be an annoyance for later? (The machine has 512 Mo of RAM) Thanks, -- Alexandre Aractingi [EMAIL PROTECTED] Want to buy your Pack or Services from MandrakeSoft? Go to http://www.mandrakestore.com
Re: [newbie] Forgot the swap partition...
as you should now, the swap partition acts like an extra ram storage... When you run applications, they alocates them code into the ram memori, but if you have varius applications running at the same time. (usualy... like network handler, video handler,database servers, and so) Each one of them will claim some memory space to work on. and if you don't have enough to bring them, the system will slow down and maybe hang. Because not all the programs work at the same time, there are memory alocated that is not nesesary to keep with the actual information and may be used by active applications, so here becomes important the swap space. At this point the SO takes the memory from the inactive applications and places it's information on the swap partition, feeing memory to use by active applications. When the unactive applications become active then the SO find's the new inactive aplications and does the hole thing again. The SO can use a non swap partition for this job, but the performance will not be the same, because the swap partition have's a diferent file sistem and method to access to the information. So if you are able to reinstall or install a extra disk to use it for swap job... go on.

Re: [newbie] Forgot the swap partition...
Thanks for your explanations! I'll create a new partition for swap use. Can I then run diskdrake to tell my OS to use it, or do I have to manually enter it in /etc/fstab?

Re: [newbie] Forgot the swap partition...
If you like the GUI, you can use the Mandrake Control Center to assign the mount point or create the new swap partition. When you finish the MCC will ask you if you whant to whrite the changes to the fstab file. And allso if you have created one swap partition and if you now the adecuated code to insert into the fstab file... go ahead. But if not, i recommend you the GUI way.
