This saves ~10% in the benchmark. Signed-off-by: Chris Marchbanks <csmarchbanks@gmail.com>
Enumerating rather than using a while loop saves significant CPU when looking for an unquoted character. This ends up improving the benchmark ~20% on its own. Signed-off-by: Chris Marchbanks <csmarchbanks@gmail.com>
Split the term into the label name and label value portions in one swoop rather than starting from the beginning to find an = character after already going through the full term. This saves ~5% on the benchmark. Signed-off-by: Chris Marchbanks <csmarchbanks@gmail.com>

Several commits that help alleviate the CPU increase reported in #1114. The performance is still worse than 0.22.1 but moving in the correct direction, and I don't know if we will be able to match performance with the additional features.
For reference, here are the benchmark results from my laptop. We still have a ways to go to get back to original peformance.
