[lttng-dev] LTTng UST vs Syslog, Printf...

[Jim Dumont]

Hi there,

Has anyone done a recent performance and characteristics comparison between lttngust with syslog and printf?   Things like memory & cpu footprint, tps, i/o, disk space...

I found this Windriver comparison from 2011: https://www.google.ca/url?sa=t&rct=j&q=&esrc=s&frm=1&source=web&cd=1&cad=rja&ved=0CCoQFjAA&url=https%3A%2F%2Fevents.linuxfoundation.org%2Fslides%2F2011%2Flinuxcon%2Flcna2011_wessel.pdf&ei=Y64TUu6qJqS62AXIqYCYCg&usg=AFQjCNF0Q05MytPYVNWBPnUjB9LEGJfQZA

And if I recall correctly, LTTng UST team also did a printf comparison a while back, but was wondering if someone has done more recent prototyping?   Any comparisons with syslog?

Regards,
