I was successfull in getting my ender 5 pro bltouch to work faster. I still have some tweaking to do, and I'm a noob. I did the following in configuration_backend.h:

I changed #define HOMING_FEEDRATE_Z 4 times 60 to 20 times 60:

#if ENABLED(EZABL_SUPERFASTPROBE) && DISABLED(BLTOUCH)
  #define HOMING_FEEDRATE_Z  (15*60)
#elif ENABLED(EZABL_FASTPROBE) && DISABLED(BLTOUCH)
  #define HOMING_FEEDRATE_Z  (8*60)
#else
  #define HOMING_FEEDRATE_Z  (20*60)
#endif

XY probe speed looks good, didn't have to change:

#if ENABLED(PROBING_MOTORS_OFF)
    #define XY_PROBE_SPEED 8000
  #else
    #if ENABLED(SLOWER_PROBE_MOVES) || ENABLED(TH3D_EZ300) || ENABLED(TIM_AM8)
      #define XY_PROBE_SPEED 8000
    #else
      #if ENABLED(EZABL_SUPERFASTPROBE)
        #define XY_PROBE_SPEED 16000
      #else
        #define XY_PROBE_SPEED 12000
      #endif
    #endif
  #endif

I uncommented this, so it probes only one time:

 //#define MULTIPLE_PROBING 2

I changed the folowing from 15, 10, 10:

#if ENABLED(BLTOUCH)
    #define Z_CLEARANCE_DEPLOY_PROBE   10
    #define Z_CLEARANCE_BETWEEN_PROBES 5
    #define Z_CLEARANCE_MULTI_PROBE    5

Hope this helps. Work in progress.

I commented (deactivated) this, so it probes only one time:

I changed the folowing from 15, 10, 10:
