looking for a new distro

How long is forever? You seem to have respectable disk I/O at 20MB/s. If it takes like 20 seconds to bring up a terminal then there is something else wrong. It very possibly could be network related (X has networking built in to it and improper networking configuration can often cause either X not to start or be very slow). What distro and version are you using again?
Also, in the top command how much % idle did it show at the top? And what did it show for memory/swap?

I thought 20 was kind of slow, is there any way (other than hdparm as i've already tried everything in there) to bring it up some? As for the top information i'll have that in a few moments... i'll just be editing this post.
so here is the top of "top":
CPU states: 6.3% user, 3.7% system, 0.0% nice, 89.9% idle
Mem: 239684K av, 123796K used, 115888K free, 0K shrd, 20596K
buff
Swap: 131092K av, 0K used, 131092K free 52584K
cached

Also look back at my previous post (just prior to this one). I added some stuff about xterm/konsole/gnome-terminal at the end while you were typing your message.
At the console of my Athlon 1600 w/512MB and a GeForce2 w/32MB running RedHat 8.0 Bluecurve Gnome it takes less than a second to start any of those three terminals, in fact I barely hit ENTER and bang, they are on my screen. From my laptop terminal servered into my Athlon xterm takes about a second, konsole takes a few seconds and gnome-terminal takes around 6 seconds (and this is starting them all over a network connection).

I've tried running xterm and it didn't take as long, it only took 3 seconds. I timed other programs...
apache configurator: 6.7 seconds
KTron: 5 seconds
the kde menu: almost a second
abiword: 4.3 seconds
I could do more but i feel i'd get the same results. I also find it sad that my lan is almost as fast as my harddrive is in linux. 20mb/second in comparison to 11mb/s (100mbps).
voidmain:
Not true. Your hard drive is 20 MegaBYTE per second. Your LAN is only 11 MegaBIT per second. 20 MB (big B) is 160Mbps compared to your 11Mbps LAN (which you will not get 11Mbps anyway because of overhead and other factors. You might get more like 7 or 8 Mbps max). And yes, often times networks can be as fast as hard drives. For instance, Gigabit network will outperform most hard drives unless you have many of them in a RAID stripe set. I am getting 32MB/s. 20MB/s is not all that bad, you may be able to get more if you play with the hdparm but I doubt it on a laptop drive. For instance, do this:
# /sbin/hdparm /dev/hda
which will list your current drive settings (dma, etc). If the settings are not optimal for your drive you can change the settings with hdparm and retest, but *be careful*, certain incorrect settings can screw up your drive. Look at the man page on "hdparm" and do a web search for more information before proceeding.

100mbps 8 bits to a byte that would make 12.5 megabytes a second. This isn't for file transfers or anything... this is just bare transfer without a protocol. Not very usefull but still, I wouldn't just include the data in a packet, but also it's header and such. I've played with hdparm for about 2 hours today with no real luck. I raised it from 19.4 to 20.51. That video driver I got seems to help a lot. i'll have to make sure i save it somewhere as I'm one of those fellas who formats about every 2 weeks or so. (i get bored and i can't stay settled) The only thing I need to do now is finish my modem, and make these damned programs load faster. i'll be back in a few, going to linux for modem stuff. thanks.
