I have been using Linux since 1993. I installed the first version of Slackware on a 16MB 386sx-25. Since then I have been using it almost exclusively on one or more of my PCs. So I consider myself as a bit of an expert. I have been using computers since 1982 mostly PCs, but also VAX mainframes and SPARC systems. Operating systems (and GUIs) I have been using include CP/M, DOS, Windows from Version 2 to XP, Geos, Beos, SCO Unix, Solaris, OS/2 and quite a few Linux Distros.
Been trying to use linux for years, this one as well as the others chuggs along really slow on my p4 2.4ghz machine!
I happen to run Mandrake 10 on a P4 2.4GHz with 512RAM and a Radeon 7500, 64MB card . The OS runs very fast and I am impressed after about a year or so of refraining from Mandrake 9.x.
My daughter's PC is a Duron 950MHz with 320RAM and a low end ATI card, 8MB I believe. She's not much of a gamer so she's very happy after switching from RH 9 (pathced from RH 8). The speed difference is very noticeable and disk swapping is rare - with OpenOffice, FireFox, Gaim and XMMS runnign all at the same time. She watches movies in XINE without any frames skipped, OpenOffice is ready to go in 32 seconds from click to ready. (18 seconds on one of my P4@2.4GHz with 512 RAM running Windows 2000Pro)
I also run a small server based on Mandrake 10.0 (recently switched from RH 9.0). It's a Celleron 700 with 320 RAM. I use it as a multipurpose server for filesharing (mp3 library of some 10000 songs and a few movies for 4 client computers), web serving (about 5000 page requests a day), a PHP development/test server and a fax server. The hardware is performing very well so I don't see the need to upgrade at this point. That particualr machine runs in non-graphical mode.
If you do have sped problems with your P4 2.4GHz then there is certainly something wrong, but I find it hard to believe it's Mandrake's fault. Therefore, I subscribe to the opinions of others that you may indeed be spreading some usual fud here.
