Slow bcrypt

[droidman]

Hi, when i benchmark bcrypt i get these speeds: (2080ti)

Hashmode: 3200 - bcrypt $2*$, Blowfish (Unix) (Iterations: 32)
Speed.#1.........:    27791 H/s (38.16ms) @ Accel:16 Loops:4 Thr:8 Vec:1

But when i try to crack a hash with pipe:

Hash.Type........: bcrypt $2*$, Blowfish (Unix)
Time.Started.....: Mon Apr 15 11:00:47 2019 (3 mins, 1 sec)
Time.Estimated...: Mon Apr 15 11:03:48 2019 (0 secs)
Guess.Base.......: Pipe
Speed.#1.........:      779 H/s (39.55ms) @ Accel:16 Loops:4 Thr:8 Vec:1

Without pipe:

Time.Estimated...: Mon Apr 15 11:53:06 2019 (48 mins, 16 secs)
Guess.Queue......: 1/1 (100.00%)
Speed.#1.........:      897 H/s (37.65ms) @ Accel:16 Loops:4 Thr:8 Vec:1

I have also tried with prince, same speeds, is there any way to make bcrypt run faster?
why is the benchmark going for 27791 H/s and a single hash going at 897 H/s ?
