測試 network (iperf3)

yum install fio

寫設定檔

設定檔可以快速的測試各種參數

nano /fio.conf

[global]
# where to test io
filename=/dev/sdb/jobfile.fio
size=10g
io_size=10g
ioengine=libaio
group_reporting
wait_for_previous

[4kSeqRead]
name=4kSeqRead

readwrite=read

[4kSeqwirte]
name=4kSeqwirte
bs=4k
readwrite=write

[4kRandRead]
name=4kRandRead
bs=4k
readwrite=randread

[4kRandwrite]

bs=4k
readwrite=randwrite


[4mSeqRead]
name=4mSeqRead
bs=4m
readwrite=read

[4mSeqwirte]
name=4mSeqwirte
bs=4m
readwrite=write

[4mRandRead]
name=4mRandRead
bs=4m
readwrite=randread

[4mRandwrite]
name=4mRandwrite
bs=4m
readwrite=randwrite

 

執行測試

fio fio.conf
rm jobfile.fio

 

測試 CPU & memory speed  (sysbench)

安裝 sysbench

https://github.com/akopytov/sysbench

Debian/Ubuntu

curl -s https://packagecloud.io/install/repositories/akopytov/sysbench/script.deb.sh | sudo bash
sudo apt -y install sysbench


RHEL/CentOS:

curl -s https://packagecloud.io/install/repositories/akopytov/sysbench/script.rpm.sh | sudo bash
sudo yum -y install sysbench

 

測試 CPU 效能

執行測試 30s 算質數數量

sysbench --threads=1 --time=60 cpu  run

結果以 total number of events 作為性能基準

root@pve1:/vm-storage# sysbench --threads=1 cpu --cpu-max-prime=1000 --time=30 run
sysbench 1.0.20 (using bundled LuaJIT 2.1.0-beta2)

Running the test with following options:
Number of threads: 1
Initializing random number generator from current time


Prime numbers limit: 1000

Initializing worker threads...

Threads started!

CPU speed:
    events per second: 18476.94

General statistics:
    total time:                          30.0001s
    total number of events:              554357

Latency (ms):
         min:                                    0.05
         avg:                                    0.05
         max:                                    1.45
         95th percentile:                        0.06
         sum:                                29875.48

Threads fairness:
    events (avg/stddev):           554357.0000/0.00
    execution time (avg/stddev):   29.8755/0.00

 

測試

以 total number of events 作為性能基準

sysbench --threads=1 --time=60 memory --memory-total-size=1024G run
