real vps server performance benchmark - the idea of this script is to predict performance of software

bench.sh

#!/bin/bash

# if memory to memory is 0kb/s then the size is too large or problem writing /run/shm 

# instant use:
#  wget -O- https://gist.githubusercontent.com/shimondoodkin/defae1e5f9c1aaabb1c7/raw/bench.sh | size=150 bash
#  wget -O- https://gist.githubusercontent.com/shimondoodkin/defae1e5f9c1aaabb1c7/raw/bench.sh | size=512 bash


# download then use
#  rm bench.sh; wget -O bench.sh  https://gist.githubusercontent.com/shimondoodkin/defae1e5f9c1aaabb1c7/raw/bench.sh
#  bash bench.sh 150 # for 150 mb file in ram
#  bash bench.sh 512

# On some vpss you could find ram at ridiculously slow speed. This script helps to compare between vpss

# the script developed for ubuntu. it is simple:
# it creates a random file intentionaly because zeros are compressable
# so it puts a file in ram then copies it: ram to ram. ram to disk ...

# maybe change count=512 to count=1024 - something above burst cache levels. but fits 2 times in ram
