Contradictory Problem of Paired Operation and dot Multiplication Operation on G1

[YYWW123]

In most cryptographic papers, the pairing operation in e:G1xG1->G2 takes much longer than the multiplication operation sP in G1. And researchers are working on pairing-free cryptographic schemes. Therefore, pairing operation should be a more time-consuming operation. Why do I use the charm library to measure that the multiplication operation in G1 is greater than the pairing operation?

Figure 1 shows the experimental data tested in Paper 1:hash to points=4.362 > pairing=4.154 > dot multiplication=1.631.
The experimental data of other people also show the same trend as Paper 1: hash to points > pairing > dot multiplication.

Figure 2 shows the data I tested with the charm library. Figure 2 shows dot multiplication=576us > pairing=468us.

I don't know what I did wrong that led to this contradictory result.

Hope to get your help, thanks!
