8257 List mode question

1.) When using list mode, loading a full list (3201 frequencies) takes over 3 full seconds using GPIB.
      Is this typical? Can it be improved by using the Ethernet interface?

2.) Our application requires switching between just a few frequencies (e.g. f0,f1,f2,f3) but over time
      adding in a small offset
     (e.g: f0,f1,f2,f3,f0,f1,f2,f3,f0+1, f1+1,f2+1,f3+1,f0+1,f1+1,f2+1,f3+1, f0+2, ...)
     We currently accomplish this by using list mode, and loading 4 frequencies at a time. The problem is
     that updating the four frequencies introduces a significant pause in the measurement. Are there
     better methods to accomplish this?

     (I've tried just loading 3201 frequencies, but the *very-slow* load time in question #1 above
      pretty much precludes that approach.)
