Indeed Ubuntu 16.04 is the previous LTS. Meanwhile 18.04 has been released and there'll be soon 20.04 Would you be interested in trying Flamegraph to find bottleneck? (see <a href="http://www.brendangregg.com/flamegraphs.html">http://www.brendangregg.com/flamegraphs.html</a>) You need a build with enable-symbols. I don't know if it's ok with enable-dbgutil but that's the reason I got 2 local builds in my machine. I know I need to type this only once for a session if I want to use Flamegraph: sh -c 'echo 1 >/proc/sys/kernel/perf_event_paranoid' (don't know if it's required for every machine) then I use these 2 alias: alias perflibo='perf record -F 200 --call-graph dwarf --pid=`pidof soffice.bin`' alias perfsvg='perf script | /home/julien/projects/FlameGraph/stackcollapse-perf.pl | /home/julien/projects/FlameGraph/flamegraph.pl --width 4096 --height 24 > perf.svg' (I just git clone Flamegraph in /home/julien/projects) perflibo is to retrieve traces perfsvg is to generate the graph.
