A little script to test terminal's performance.

terminal_benchmark.sh

#!/usr/bin/env bash
# Generate 100MB of random tex.
cat /dev/urandom | base64 | dd of=/tmp/randomdata bs=1024 count=100k

# Test. Repeat for each terminal...
# Results are written to bench_XXX.txt
# This also shows MB/s very nicely thanks to `dd`.
{ time dd if=/tmp/randomdata bs=10240; } 2> bench_XXX.txt
