Group Commits Vs WAL Writes - Mailing list pgsql-hackers

Hi all,

I think this is a naive question.

When we do a commit, WAL buffers are written to the disk. This has a
disk latency for the required I/O.

Now, with group commits, do we see a spike in that disk write latency,
especially in the cases where the user has set wal_buffers to a high
value?
