All the programs mentioned by you are relatively memory-intensive. How much memory do you have installed and what OS/desktop is your computer running?
To confirm a possible memory shortage do the following: open a shell window and issue
Let it run for some lines of output until the output is relatively stable. Now start the two programs in question and watch the change in the display. You should be able to see the free memory amount dropping and at the same time the swap activity going up. This would confirm a memory shortage.
The only way to cure such a problem is putting more memory in.
I hope this helps.

I have a dual boot of Fedora and XP. I use Fedora way more often though. I have 4 GB of ram and a 4 GB swap. 4 GB of ram is the maximum with this computer.
Is this part a mistake?
Shouldn't I touch that file to create it first?
Why do you think it is ram instead of cpu issue? I was thinking it was a cpu issue. Ram is much easier to replace so I hope your right.

MD(4) BSD Kernel Interfaces Manual MD(4)NAME
md -- memory disk
SYNOPSIS
device md
DESCRIPTION
The md driver provides support for four kinds of memory backed virtual disks:
malloc Backing store is allocated using malloc(9). Only one malloc-bucket is used, which means that all md devices with malloc backing
must share the malloc-per-bucket-quota. The exact size of this quota varies, in particular with the amount of RAM in the system.
The exact value can be determined with vmstat(8).
preload A file loaded by loader(8) with type 'md_image' is used for backing store. For backwards compatibility the type 'mfs_root' is also
recognized. If the kernel is created with option MD_ROOT the first preloaded image found will become the root file system.
vnode A regular file is used as backing store. This allows for mounting ISO images without the tedious detour over actual physical media.
swap Backing store is allocated from buffer memory. Pages get pushed out to the swap when the system is under memory pressure, otherwise
they stay in the operating memory. Using swap backing is generally preferable over malloc backing.
For more information, please see mdconfig(8).
EXAMPLES
To create a kernel with a ramdisk or MD file system, your kernel config needs the following options:
options MD_ROOT # MD is a potential root device
options MD_ROOT_SIZE=8192 # 8MB ram disk
makeoptions MFS_IMAGE=/h/foo/ARM-MD
options ROOTDEVNAME="ufs:md0"
The image in /h/foo/ARM-MD will be loaded as the initial image each boot. To create the image to use, please follow the steps to create a
file-backed disk found in the mdconfig(8) man page. Other tools will also create these images, such as NanoBSD.
SEE ALSO disklabel(8), fdisk(8), loader(8), mdconfig(8), mdmfs(8), newfs(8), vmstat(8)HISTORY
The md driver first appeared in FreeBSD 4.0 as a cleaner replacement for the MFS functionality previously used in PicoBSD and in the FreeBSD
installation process.
The md driver did a hostile takeover of the vn(4) driver in FreeBSD 5.0.
