I'm finding that my Syslog-NG 2.0.9 OSE is not able to send more than 19
msgs/sec.
source s_ldsol01_file {
        file("/tmp/ldsol01-clog.log"
             follow_freq(10)
             flags(no-parse)
             log_fetch_limit(1000)
             log_iw_size(2000)
        );
};
You're polling the file every 10 seconds (follow_freq() is in seconds,
not milliseconds) and reading a maximum of 1000 messages per
iteration, so your maximum possible throughput is 100 msgs/sec.

That's still quite a bit higher than the 19 you're seeing, but you
might want to try dropping the value of follow_freq to 1 and see if
that shows an improvement.
