 If I run

 {{{
 # sysbench --test=cpu run
 sysbench 0.4.12:  multi-threaded system evaluation benchmark

 Running the test with following options:
 Number of threads: 1

 Doing CPU performance benchmark

 Threads started!
 Done.

 Maximum prime number checked in CPU test: 10000

 Test execution summary:
     total time:                          15.9531s
     total number of events:              10000
     total time taken by event execution: 15.9465
     per-request statistics:
          min:                                  1.18ms
          avg:                                  1.59ms
          max:                                  9.27ms
          approx.  95 percentile:               2.08ms

 Threads fairness:
     events (avg/stddev):           10000.0000/0.00
     execution time (avg/stddev):   15.9465/0.00

 For comparison, running it with a single thread on this PC with a 3.4GHz
 Ryzen CPU, it takes 10 seconds, 2/3rds of the time.

 lscpu tells me the VPS has a Intel(R) Xeon(R) CPU E5-2630L v2 @ 2.40GHz,
 and a BogoMIPS:              of 4800. This PC has one of 6800.

 It's not a lack of CPU power.
