This contains some small tweaks to speed up the profiler. - changed from a namedtuple to a regular tuple as namedtuples were much slower but the tradeoff here is that it's more legible - moved away from `os.path.abspath` as it was doing some extra operations that were unnecessary for our use case
The sample buffer kept 30s of samples around in memory. This introduces a noticeable memory overhead on systems with less memory available. This change removes the buffer and directly writes to the profile itself where the sample is processed on the fly instead of at the end.
