why Hashcat v6.2.5 is slower than v5.1.0
#8
as for the given cracking speed i didnt see any differences between 5.1 and 6.2.5, as PDO mentioned initializing runtime backend isnt your friend

take a look at your hashcat -I output it tells opencl 1.2 which is old it should tell

Code:
OpenCL Platform ID #1
  Vendor..: Intel(R) Corporation
  Name....: Intel(R) OpenCL
  Version.: OpenCL 2.1

  Backend Device ID #1 (Alias: #2)
    Type...........: CPU
    Vendor.ID......: 8
    Vendor.........: Intel(R) Corporation
    Name...........: Intel(R) Xeon(R) Silver 4116 CPU @ 2.10GHz
    Version........: OpenCL 2.1 (Build 0)
    Processor(s)...: 48
    Clock..........: 2100
    Memory.Total...: 130722 MB (limited to 16340 MB allocatable in one block)
    Memory.Free....: 65329 MB
    Local.Memory...: 32 KB
    OpenCL.Version.: OpenCL C 2.0
    Driver.Version.: 18.1.0.0920

at least, see diff in opencl versiosn and driver version

second thing, runnning hashcat directly from C: is mostly a bad idea due to windows don't like such programs directly on the system drive, as im writing these lines and testing on windows myself i recognized some strange behavior from the windows defender (win 10 up2date)

windows defender gives repeatedly an popup (your admin advised some security online checking for an element or something similar) and hashcat isnt starting for a long time, i suspect the defender blocking hashcat and hashcat has to use something like a emulator layer to use the old opencl style instead

next thing to try, please update your opencl runtime from intel as DPO mentioned
