* etc/systemd/zfs-mount-generator: serialise The wins for a relatively normal workload are rather slim: real 0.02119s/0.00985s=2.15029x user 0.02130s/0.00346s=6.15560x sys 0.03858s/0.00643s=6.00062x wall-total 0.014518s/0.005925s=2.45009x wall-init 0.014518s/0.002457s=5.90684x wall-real 0.014518s/0.003467s=4.18668x But this is a big win on machines with a lot of datasets and expensive forks. For example, the gain on a VM on my work laptop with 900+ legacy-mount Docker datasets, the original gains from the C rewrite were only five-fold: real 0.516s/0.102s=5.05882x user 0.237s/0.143s=1.65734x sys 0.287s/0.100s=2.87x And this serial variant gains this back there as well: real 0.102s/0.008s=12.75x user 0.143s/0.007s=20.42857 sys 0.100s/0.001s=100x wall-total 0.09717s/0.00319s=30.40255x wall-init 0.00203s/0.00200s=1.015941x wall-real 0.09513s/0.00118s=80.02043x For a total of real 0.516s/0.008s=64.5x user 0.237s/0.007s=33.85714x sys 0.287s/0.001s=287x Suggested-by: Richard Laager <rlaager@wiktel.com> * etc/systemd/zfs-mount-generator: pull in network for keylocation=https Also simplify RequiresMountsFor= handling Ref: #11956 Reviewed-by: Richard Laager <rlaager@wiktel.com> Reviewed-by: Tony Nguyen <tony.nguyen@delphix.com> Signed-off-by: Ahelenia Ziemiańska <nabijaczleweli@nabijaczleweli.xyz> Closes #12138 |
