 |
|
Are parallel emerge jobs being plagued by a bottleneck? I don't see multiple packages being merged:
| Code: | >>> Installing (53 of 1573) acct-group/systemd-journal-remote-0-r3::gentoo
>>> Completed (53 of 1573) acct-group/systemd-journal-remote-0-r3::gentoo
>>> Installing (54 of 1573) acct-group/nobody-0-r2::gentoo
>>> Completed (54 of 1573) acct-group/nobody-0-r2::gentoo
>>> Installing (55 of 1573) acct-group/portage-0-r2::gentoo
|
This goes on and on, two lines at once completed immediately followed by installing then pause and the next pair of lines, the jobs have been started long ago. I thought since it doesn't have much work to do it would be merging them faster but am I wrong?
Best Regards,

| Merging simply can't be parallized in a safe way as every merge process alters the system state (unlike build jobs that are isolated). Also it is questionable if you'd actually see major performance improvements anyway as they'd usually all end up hammering the same storage device. |

But it still happens noticeably slow? Is there something different about merging binary packages? For smaller packages it's sure seem to take more time than source based build.
