i want to test several linux VPS using bench mark tools
as i reead there are 2 indestry standart tools called unixBench and SysBench
I compiled them and executed them on the VPS
And i have results :
SysBench:( 4 CPU)

./sysbench --test=cpu --cpu-max-prime=20000 --num-threads=4 run

The result :

General statistics:
 total time: 3.222s
 total number of events: 10000

Latency (ms):
 min: 1.64
 avg: 5.76
 max: 6.19
 95th percentile: 3.00
 sum: 60000.86

Threads fairness:
 events (avg/stddev): 30000.0000/2.00
 execution time (avg/stddev): 8.0002/0.00

from reading i know that the important info is in : total time: 3.222s
ok .. but compared to what ?
how can i know that this is good result ?
also what about the other parameters ? like 95th percentile
what does it means ?

Now running UnixBench ( 4 CPU )

./Run -c 4

The result :

BYTE UNIX Benchmarks (Version 5.1.3)

Here again i know i should look at the :
System Benchmarks Index Score 1157.3

but again the question raised this result is compared to what ?
how should i know if this total result is good ? bad ? average ?
Thanks

Quoting the USAGE file of UnixBench,

Interpreting the results of these tests is tricky, and totally depends on what you're trying to measure.

In your case you want to "test several linux VPS" so for starters you can rank them according to the index (or according to specific indicators you can find in the test, if you know exactly what you are looking for).

In order to know how well a machine performs "in general" (that is to say, in comparison to all machines ever used for similar needs), one would need a large database reporting benchmarks categorized by hardware and OS (and maybe other specs).
It seems that http://linux-bench.com/ is a step towards this, which would be useful not only to know the above, but also to confirm suspicion of hardware not working as well as it should. Unfortunately, in my opinion the current "results" section is not rich enough, contains aberrant results, and does not indicate enough information about the different systems tested.
