bc272e9f7c Represent speed in GCTracer functions as double instead of int. 
This avoids redundant casts, loss of precision, and potential overflows.

c42b2c4493 Refactor the ring buffer in GCTracer. 
Now instead of saving all event details in the ring buffer,
we save only the bytes and duration.

This reduces the GCTracer size from 20K to 3K and simplifies code.
