How did you determine they are slow. How long do you think they should take? How long would it normally take? How long does it now take? How many devices are in the vary command at one time?
What analysis have you done to determine "slow" What timings do you get when you vary one device compared to 10 compared to 100? Do you see any error messages indicating the commands are not processing? Have you issued the CMDS command to see what is going on at the same time as the slow commands?
