Using the attached config file on a Linux Redhat Server 6.3 I can only get approx 2,000 messages per second

cat ~/some.log >> /var/log/syslog.pipes/test


Using the same config file (with @version 3.3) using 3.3.7 I can process 50,000+ messages per second.

By enabling threaded(yes) I can get 50,000+ messages per second.
