Commit message from 2.4:
Running a test on Windows using a pubring.kbx with
Total number of blobs: 2098
openpgp: 1294
x509: 803
and a size of 42MiB with
gpgsm -k --with-validation --disable-dirmngr --kbx-buffer-size N >nul
gives these performance figures using procmon
| N(k) | file events | time(s) |
|------+-------------+---------|
| 0 | 4900000 | 86 |
| 16 | 2456000 | 58 |
| 32 | 1233000 | 43 |
| 64 | 622000 | 37 |
| 128 | 317000 | 32 |
| 256 | 164000 | 31 |
| 512 | 88000 | 30 |
Using _open instead of CreateFile give the same number of file events
but increased the time slight by one second for the measured buffer
size of 64k and 128k. Benchmarks for gpg have not been conducted.
