  • In conclusion

The gurl command can send more messages per second (12w/s) than the ab(3w/s) command. The more cores, the higher the performance of "gurl" than "ab".The reason "gurl" is faster than "ab" is that ab only uses a single thread for pressure testing, and is particularly dependent on the cpu clock speed. The fast clock speed runs faster.
