> Does FreeBSD softupdates

Softupdates have a dramatic effect on the time spent when creating,
renaming and removing files with FFS. The effect on reading or
writing files is modest, at most.

That's appending data to a file. Therefore, softupdates have little
effect, if any effect at all. Softupdates try to avoid disk I/O.
Synchronous syslogging forces disk I/O to happen.

> 2. Reduce likelihood of losing logs upon power trip or whatnot?

I suppose you are comparing FFS with softupdates against FFS without
softupdates.

No difference with synchronous syslog writing. Syslogd waits until
the data is written to disk.

No difference is expected without synchronous syslog writing.
