[#3]Re: Long term test on Apache VM is running

[冯 庆新 <qi...@hotmail.com>]

Hello  all :



Last week we try to increase the cache number for evaluating the stability of IoTDB.



Now I will report the result to you:

Start Time: 2019-06-05 08:26:12

End Time: 2019-06-06 13:50:26

Total elapse time: 105846 second

Timeseries Num : 100,000 [1000 Devices * 100 Sersors]

Loaded 20000000000points in 47857.383s with 4workers (mean rate 417908.34 points/s)

Total Operations 200000; Latency(ms): Avg 950.4918, MiddleAvg 923.244, Min 785, Max 52390

Total error num is 0.

 ///////////////////////////////////////////////////////////////////////////

### client mode ###

CLIENT_NUMBER=4

GROUP_NUMBER=10

DEVICE_NUMBER=1000

SENSOR_NUMBER=100

CACHE_NUM=1000

LOOP=200 [ limited by disk - 200G ]

///////////////////////////////////////////////////////////////////////////

Next time we will try to increase the number of time series to 200,000[1000 Devices and 200 Sensors].



That’s all.

Please feel free to contact me if you have any questions

Thank you.

Best Reagrds!
