Subject: [PATCH] Increase the ext4 default commit age
|
||
|
|
|
||
|
|
Both the VM and EXT4 have a "commit to disk after X seconds" time.
|
||
|
|
Currently the EXT4 time is shorter than our VM time, which is a bit
|
||
|
|
suboptional,
|
||
|
|
it's better for performance to let the VM do the writeouts in bulk
|
||
|
|
rather than something deep in the journalling layer.
|
||
|
|
|
||
