Changing the parameters in default.ini has no effect on running speed. Why?

When I increased the number of md simulation steps (nsteps) to 5000000 by editing default.ini file. But the running speed did not correspondingly decreased. The new edited *.int file was executed by using -c flag.

Could you please show me your int file? See the https://github.com/dptech-corp/Uni-GBSA/blob/master/unigbsa/data/default.ini file for details. You need to change the parameter of mode in [simulation] to md, like this:

; parameters for simulation
[simulation]
; input pose process method: 
;   input   -   just use input pose to calculation
;   em      -   run a simple energy minimizaion for the input poses
;   md      -   run a md simulation for the input poses
mode = md
