that split and merge load are not universal constants and many file
factors affect the optimal values for them. What I don't understand is

it would help to have some specific information about your file - such as -
what is the split/merge type?
Here you go Wally. :)
Number of groups in file (modulo) = 4766568
Minimum groups of file= 1192027
Hash type = 0, blocksize = 1024
Split load = 20, Merge load = 10
