How to read the data from SysBench And UNIXBench when testing VPS?

i want to test several linux VPS using bench mark tools
as i read there are 2 industry standard tools called unixBench and SysBench
I compiled them and executed them on the VPS
And i have results :

Code:
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 )


Code:
    ./Run -c 4

The result :

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
