Confirm the condition of the instance
Before doing a benchmark test, let's check the current instance's available memory and CPU type.
free -m
The command to check the memory.
The status is displayed as the following:
[root@ip ~]# free total used free shared buff/cache available Mem: 3618884 230312 3196636 26304 191936 3187852 Swap: 9433084 0 9433084
Information displayed by the "free-m" command
In this example, we confirm that approximately 3.5GB can be used.
Next we will check the CPU.
cat /proc/cpuinfo
The command to check the CPU type.
The results will be like the following:
[root@ip- ~]# cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 63 model name : Intel(R) Xeon(R) CPU E5-2676 v3 @ 2.40GHz stepping : 2 microcode : 0x25 cpu MHz : 2400.036 cache size : 30720 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 13 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx rdtscp lm constant_tsc rep_good nopl xtopology eagerfpu pni pclmulqdq ssse3 fma cx16 pcid sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand hypervisor lahf_lm abm fsgsbase bmi1 avx2 smep bmi2 erms invpcid xsaveopt bogomips : 4800.07 clflush size : 64 cache_alignment : 64 address sizes : 46 bits physical, 48 bits virtual power management: processor : 1 vendor_id : GenuineIntel cpu family : 6 model : 63 model name : Intel(R) Xeon(R) CPU E5-2676 v3 @ 2.40GHz stepping : 2 microcode : 0x25 cpu MHz : 2400.036 cache size : 30720 KB physical id : 0 siblings : 2 core id : 1 cpu cores : 2 apicid : 2 initial apicid : 2 fpu : yes fpu_exception : yes cpuid level : 13 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx rdtscp lm constant_tsc rep_good nopl xtopology eagerfpu pni pclmulqdq ssse3 fma cx16 pcid sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand hypervisor lahf_lm abm fsgsbase bmi1 avx2 smep bmi2 erms invpcid xsaveopt bogomips : 4800.07 clflush size : 64 cache_alignment : 64 address sizes : 46 bits physical, 48 bits virtual power management:

In this example, a dual-core 2.4GHx "Xeon CPU E5-2676 v3" was assigned.
