IBM SoftLayer
The following test was executed on the IBM SoftLayer Bare Metal Server
Single Intel Xeon E3-1270 v3: 8vCPU(3.50 GHz) + 32GB(DDR3) + SSDs(400GB)To see test result on
PacketBare Metal Server
1. Time
1.1 Pod startup time
Run a new Pod only takes 336 millisecond(ms).
- | min(ms) | max(ms) | avg(ms) |
startup time | 314 | 366 | 336 |
The following tests are for "Hyper for KVM" with qboot
1.2 Pod replace time
Replace a running Pod with a new one, only takes 95 ms.
- | min(ms) | max(ms) | avg(ms) |
replace time | 80 | 107 | 95 |
2. Memory Utilization
2.1 Minimum startup memory
The minimum startup memory is 28(MB)
2.2 QEMU process memory usage
When starting a Pod with minimum startup memory, QEMU process uses 49MB physical memory in Host OS.
- | min(MB) | max(MB) | avg(MB) |
RSS(VmRSS) | 48 | 50 | 49 |
VSZ(VmSize) | 437 | 438 | 438 |
2.3 Memory usage in Pod
When start a Pod with minimum startup memory, there will be 9MB free memory in a running Pod. Hyper Kernel only takes 11MB memory.
- | min(MB) | max(MB) | avg(MB) |
Total | 21 | 21 | 21 |
Used | 11 | 11 | 11 |
Free | 9 | 10 | 9 |
3. CPU Performance
Allocation of resources: 2 CPU, 2048GB Memory
The following table is the result of sysbench CPU performance test. CPU performances in Hyper are pretty close to Host OS.
Target | num-threads | cpu-max-prime | total time(sec) | resp min(ms) | resp avg(ms) | resp max(ms) |
Host | 1 | 10000 | 9.88 | 0.95 | 0.99 | 1.01 |
Docker | 1 | 10000 | 9.89 | 0.95 | 0.99 | 1.12 |
Hyper | 1 | 10000 | 9.92 | 0.95 | 0.99 | 1.28 |
Host | 2 | 50000 | 45.81 | 8.51 | 9.16 | 9.39 |
Docker | 2 | 50000 | 45.83 | 8.50 | 9.16 | 13.17 |
Hyper | 2 | 50000 | 45.97 | 8.95 | 9.19 | 10.22 |
In the Target column,
Hostmeans Host OS,Dockermeans Docker container,Hypermeans Hyper Pod
4. Memory Performance
Allocation of resources: 2 CPU, 2048GB Memory Test parameter: 1MB block size, transfer datasize is 100GB.
The following table is the result of sysbench memory performance test.
Target | num-threads | rnd-read(MB/sec) | rnd-write(MB/sec) | seq-read(MB/sec) | seq-write(MB/sec) |
Host | 1 | 11497 | 11489 | 11487 | 11513 |
Docker | 1 | 11494 | 11491 | 11494 | 11505 |
Hyper | 1 | 11417 | 11439 | 11418 | 11419 |
Host | 2 | 22926 | 22835 | 22694 | 22770 |
Docker | 2 | 22593 | 22828 | 22629 | 22900 |
Hyper | 2 | 22608 | 22647 | 22737 | 22741 |
