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 Packet Bare 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, Host means Host OS, Docker means Docker container, Hyper means 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
