There are many tutorials in Google 'how to benchmark XXX'.
In this thread are tools I tested on Ubuntu 20.04.

With all these tests, it should be easy to compare VPSes and Cloud offers from different companies.

1. CPU

1.1 CPU - 7zip compress/decompress
Install:
Code: 
sudo apt install p7zip-full
Run single thread test:
Code: 
7z b -mmt1
Run multi thread test [auto-detects number of cores/threads in CPU]:
Code: 
7z b

1.2 CPU - sysbench
Install:
Code: 
sudo apt install sysbench
Run tests with 1, 2, 4 and 16 threads:
Code: 
sysbench cpu --threads=1 run
sysbench cpu --threads=2 run
sysbench cpu --threads=4 run
sysbench cpu --threads=16 run
FOR OLD VERSION of sysbench - Debian 9 etc. - run tests with 1, 2, 4 and 16 threads:
Code: 
sysbench --num-threads=1 --test=cpu run
sysbench --num-threads=2 --test=cpu run
sysbench --num-threads=4 --test=cpu run
sysbench --num-threads=16 --test=cpu run

2. RAM

2.1 RAM - transfer
Install:
Code: 
sudo apt install sysbench
Run tests with 1, 2, 4 and 16 threads:
Code: 
sysbench memory --memory-block-size=1M --memory-total-size=1G --threads=1 run
sysbench memory --memory-block-size=1M --memory-total-size=1G --threads=2 run
sysbench memory --memory-block-size=1M --memory-total-size=1G --threads=4 run
sysbench memory --memory-block-size=1M --memory-total-size=1G --threads=16 run
FOR OLD VERSION of sysbench - Debian 9 etc. - run tests with 1, 2, 4 and 16 threads:
Code: 
sysbench --test=memory --memory-block-size=1M --memory-total-size=1G --num-threads=1 run
sysbench --test=memory --memory-block-size=1M --memory-total-size=1G --num-threads=2 run
sysbench --test=memory --memory-block-size=1M --memory-total-size=1G --num-threads=4 run
sysbench --test=memory --memory-block-size=1M --memory-total-size=1G --num-threads=16 run

2.2 RAM - operations per second
Install:
Code: 
sudo apt install sysbench
Run tests with 1, 2, 4 and 16 threads:
Code: 
sysbench memory --memory-block-size=1k --memory-total-size=1G --threads=1 run
sysbench memory --memory-block-size=1k --memory-total-size=1G --threads=2 run
sysbench memory --memory-block-size=1k --memory-total-size=1G --threads=4 run
sysbench memory --memory-block-size=1k --memory-total-size=1G --threads=16 run
FOR OLD VERSION of sysbench - Debian 9 etc. - run tests with 1, 2, 4 and 16 threads:
Code: 
sysbench --test=memory --memory-block-size=1K --memory-total-size=1G --num-threads=1 run
sysbench --test=memory --memory-block-size=1K --memory-total-size=1G --num-threads=2 run
sysbench --test=memory --memory-block-size=1K --memory-total-size=1G --num-threads=4 run
sysbench --test=memory --memory-block-size=1K --memory-total-size=1G --num-threads=16 run

3. Network connection speed

3.1 Network - transfer
Install:
Code: 
sudo apt-get install curl
curl -s https://install.speedtest.net/app/cli/install.deb.sh | sudo bash
sudo apt-get install speedtest
Run test:
Code: 
speedtest

4. Disk (HDD/SSD)

4.1 dd - write transfer
  • If test takes longer than 30 seconds, ignore tests with bigger files.
  • Increase file size to make test run longer than 10 seconds. We want to get real disk write speed, not disk cache speed.
Code: 
# 128 MB
dd if=/dev/zero of=/tmp/output.img bs=16M count=8

# 256 MB
dd if=/dev/zero of=/tmp/output.img bs=16M count=16

# 1 GB
dd if=/dev/zero of=/tmp/output.img bs=16M count=64

# 4 GB
dd if=/dev/zero of=/tmp/output.img bs=16M count=256
Cleanup after tests - do not cleanup, if you want to run test '4.2 read transfer':
Code: 
rm /tmp/output.img

4.2 dd - read transfer
In this test we read file created in 'write transfer test'. If you stopped write tests on 1 GB file, you cannot run 4 GB 'read test'.
  • If test takes longer than 30 seconds, ignore tests with bigger files.
  • Increase file size to make test run longer than 10 seconds. We want to get real disk read speed, not disk cache speed.
You got to cleanup Linux cache before every test with sync; echo 3 > /proc/sys/vm/drop_caches.
Code: 
# 128 MB
sync && echo 3 > /proc/sys/vm/drop_caches && dd if=/tmp/output.img of=/dev/null bs=16M count=8

# 256 MB
sync && echo 3 > /proc/sys/vm/drop_caches && dd if=/tmp/output.img of=/dev/null bs=16M count=16

# 1 GB
sync && echo 3 > /proc/sys/vm/drop_caches && dd if=/tmp/output.img of=/dev/null bs=16M count=64

# 4 GB
sync && echo 3 > /proc/sys/vm/drop_caches && dd if=/tmp/output.img of=/dev/null bs=16M count=256
Cleanup after tests:
Code: 
rm /tmp/output.img

4.3 fio - write IOPS [operations per second]
  • If test takes longer than 30 seconds, ignore tests with bigger files.
  • Increase file size to make test run longer than 10 seconds. We want to get real disk write speed, not disk cache speed.

sudo apt-get install fio

# 64 MB
fio --randrepeat=1 --ioengine=libaio --direct=1 --gtod_reduce=1 --name=test --filename=test --bs=4k --iodepth=64 --size=64M --readwrite=randwrite

# 128 MB
fio --randrepeat=1 --ioengine=libaio --direct=1 --gtod_reduce=1 --name=test --filename=test --bs=4k --iodepth=64 --size=128M --readwrite=randwrite

fio --randrepeat=1 --ioengine=libaio --direct=1 --gtod_reduce=1 --name=test --filename=test --bs=4k --iodepth=64 --size=4G --readwrite=randwrite
Cleanup after tests:
Code: 
rm test

4.4 fio - read IOPS [operations per second]

fio --randrepeat=1 --ioengine=libaio --direct=1 --gtod_reduce=1 --name=test --filename=test --bs=4k --iodepth=64 --size=128M --readwrite=randread

# 512 MB
fio --randrepeat=1 --ioengine=libaio --direct=1 --gtod_reduce=1 --name=test --filename=test --bs=4k --iodepth=64 --size=512M --readwrite=randread

fio --randrepeat=1 --ioengine=libaio --direct=1 --gtod_reduce=1 --name=test --filename=test --bs=4k --iodepth=64 --size=1G --readwrite=randread

# 4 GB
fio --randrepeat=1 --ioengine=libaio --direct=1 --gtod_reduce=1 --name=test --filename=test --bs=4k --iodepth=64 --size=4G --readwrite=randread
Cleanup after tests:
Code: 
rm test

4.5 ioping - latency
This test takes 60 seconds and checks how stable is disk access time (latency).
Install:
Code: 
sudo apt-get install ioping
Run test:
Code: 
ioping -c 60 .

1.2 CPU - sysbench
General statistics:
total time: 10.0008s
total number of events: 206746
Click to expand...
To make it easier to compare score with other versions of sysbench, you should divide number of events by number of seconds.
In case of score above, it would be 206746 / 10 = 20675 events per second.
