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 commented (deactivated) 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.
