  Finding heavy hitters has been of vital importance in network measurement.
Among all the recent works in finding heavy hitters, the Elastic sketch
achieves the highest accuracy and fastest speed. However, we find that there is
still room for improvement of the Elastic sketch in finding heavy hitters. In
this paper, we propose a tailored Elastic to enhance the sketch only for
finding heavy hitters at the cost of losing the generality of Elastic. To
tailor Elastic, we abandon the light part, and improve the eviction strategy.
Our experimental results show that compared with the standard Elastic, our
tailored Elastic reduces the error rate to 5.7~8.1 times and increases the
speed to 2.5 times. All the related source codes and datasets are available at
Github.
