# nench.sh ("new bench.sh")
|
|
# =========================
|
|
# current version at https://github.com/n-st/nench
|
|
# - loosely based on the established freevps.us/bench.sh
|
|
# - includes CPU and ioping measurements
|
|
# - reduced number of speedtests (9 x 100 MB), while retaining useful European
|
|
# and North American POPs
|
|
# - runs IPv6 speedtest by default (if the server has IPv6 connectivity)
|
|
# Run using `curl -s bench.wget.racing | bash`
|
|
# or `wget -qO- bench.wget.racing | bash`
