How fast is DES?

Guten Tag!

  Due to the complexity of the DES algorithm involving various bit
swapping and table lookup operations during multiple iterations I am
wondering how fast the DES is in praxis.

  Is it possible for a software solution to reach an encryption rate
of about 100kB/sec (read 100 * 1024 Byte not 100 * 1024 Bit per second)
on a typical PC (say, Intel 386DX 33MHz)?

  If not: are there any other secure encryption/decryption algorithms
which are running faster?

  Any information will be appreciated. Many thanks in advance for your
help!
