I thought, that would be fast. I can choose the format that 
is best. (But probably, I 'd like to have a text format.)
So I could shoose 
abc def
too.

Yes.

Now I have changed my program to

    i = -1
    print 'loading file'
    def tmp1(s,color=self.sv.lv.newColor):
      global i
      i += 1
      j = string.find(s,' ')
      return QSimpleViewItem(i,color,[s[:j],s[j+1:-1]])

    try:
      myfile = open(filename)
    except:
      pass
    else:
      tmp = myfile.readlines()
      print 'lines loaded'
      myfile.close()
      self.sv.lv.rows = map(tmp1,tmp)
      self.sv.lv.visible = range(len(self.sv.lv.rows))
      print 'lines decoded',self.sv.lv.rows[0].col[0]

This is really faster. I did not undertand, how to get rid 
of the global variable <i>, but even if I do not use i at 
all and replace it by 0, the time I need is the same.
