I don't understand how you took that conclusion. The explanations refer
to the default log size. I believe the original poster asked about the
performance advantage of *raising* the log size above the default values
for internal logs,
I was under the assumption that the OP asked about altering the size of
the log at all and the manpage only states a reason for *decreasing* the
logsize.
and my impression is that metadata-intensive
workloads benefit from increasing the log size (however no hard numbers
are available).
As no numbers are known to me either, I did not see a point in
increasing the log, hence my statement.
A while back when mkfs.xfs had more conservative default value, bigger log
sizes indeed helped for big filesystems.
As I've done a few benchmarks[0] for different filesystems lately I
might find some time to play around with different fs tweaks...
