How long is it supposed to take to complete one work unit? I have climate prediction running round the clock with 3/4 of time going to it and it has not even broke the %2 mark yet!!

Since you are running multi project you should change your preferences to leave projects in memory while they are paused. The current version of BOINC does not wait until a checkpoint to switch, and all work since the last checkpoint is discarded if a project is removed from memory.
