[syslog-ng] Multi-threaded in open source?

[Avleen Vig]

Hi everyone,

I'm running an infrastructure with several hundred hosts logging many
hundreds of Gb of logs to a central server.
Syslog-ng on the central server is using 100% CPU on a single core,
and I see here:
    http://bazsi.blogs.balabit.com/2011/07/syslog-ng-multithreaded-performance/
that there is some multi-threading option available!

Is this only in the PE version or is there an OSE edition with this feature?
