mace performance

Hi experts,

I did some test to trouble shoot performance issue and found that for the same expression and same local domain, the time it took differs when I use different mace arguments.

Case 1:

time mace -d <global_domain>/<local_domain> -run -expression "AWpMapStAsoBo = If(AWpMapStAsoClBo, TRUE, FALSE)"

real    51m34.002s

user    5m20.776s

sys     45m41.722s

Case 2:

time mace -d <global_domain> -run -expression "AWpMapStAsoBo = If(AWpMapStAsoClBo, TRUE, FALSE)" -processes 50

real    121m8.481s

user    32m57.932s

sys     1607m11.321s

The expression is pretty much like the one suggested in session   "A = if(condition, B, 0)"

The local domain is the biggest one and in Case 2 it also takes the longest to finish.
