After some simple profiling on a Lx7 x86_64 real hardware target, I see in "top" that the tcf-agent is 228MB large. After some memory instrumentation with perf uprobes, I have seen it 580MB large. This is surprising and unexpected since doing the same workflow on qemux86 it seems to grow only to 37MB. It may be OK taking memory that's available and not used otherwise, but I wanted to raise a flag to get this investigated.
