Subjectftrace: trace buffer size configuration
From
Hi,

I'am using ftrace to trace my system for a few minutes. For that I
configured the trace buffer via buffer_size_kb file to 100000 kb so 200000
for 2 CPUs. After tracing my system the trace size is 500MB.
Why the allocated size for the trace buffer (200 MB) is not the same of the
trace file (500 MB) ?

and is it convenient to allocate such a big size for the buffer?

Best regards
