Re: Very slow bcache-register: 6.4TB takes 10+ minutes

[Teodor Milkov <tm@xxxxxx>]

Just for the record -- here are the times to register a cache device vs. 
how full it is (used % from priority_stats):

||  GB ||     Time || GB/s ||
|  111 |   0m10.8s |  10.3  |
|  209 |   0m20.3s |  10.3  |
|  433 |   0m43.1s |  10.0  |
|  931 |   1m41.6s |   9.2  |
| 1695 |   3m11s   |   8.9  |

This is on Intel DC P3500 series 2TB NVMe drive +
Xeon Silver 4114 CPU @ 2.20GHz.
