[Report] Optimize remote-trait-object

[junha1]

Here's an instruction to profile the program.

cargo install flamegraph
sudo apt-get install linux-tools-5.3.0-62-generic
echo -1 | sudo tee /proc/sys/kernel/perf_event_paranoid
echo 0 | sudo tee /proc/sys/kernel/kptr_restrict
cargo flamegraph

I will constantly report benchmark result here.
