   Here I share the pressure measurement data:
   program execution time：30min
   provider logic：direct new object return
   provider thread pool size：800
   consumer timeout：1s
   provider timeout：default
   service agreement：dubbo
   
   result:
   
   consumer concurrent | tcp links | total invoke times | invoke fail（timeout）times | service invoke success rate | service invoke QPS | service invoke avg cost time | invoke time more than 100ms rate | （consumer cost time - provider cost time） avg time
   500 | 3links | 49287931 | 1771 | 99.9964% | 27271 | 18.1ms | 0.006% | 0.31ms
   500 | 2links | 47601583 | 1141 | 99.9976% | 26464 | 18.9ms | 0.006% | 0.38ms
   500 | 2links | 47871439 | 1146 | 99.9976% | 26919 | 18.7ms | 0.006% | 0.41ms
   500 | 1links | 46258320 | 1051 | 99.9977% | 25702 | 18.8ms | 0.007% | 8.99ms
   500 | 1links | 46421769 | 1005 | 99.9978% | 25910 | 18.7ms | 0.007% | 9.84ms
   200 | 3links | 55025248 | 478 | 99.9991% | 31066 | 6.4ms | 0.004% | 0.16ms
   200 | 1links | 47376374 | 255 | 99.9995% | 26362 | 7.1ms | 0.003% | 4.89ms
   100 | 2links | 55366764 | 0 | 100% | 30640 | 3.2ms | 0.0002% | 0.13ms
   
   We can see that in the case of concurrent 500 calls, the throughput of two tcp connection transmissions is 3.5% higher than that of one tcp connection transmission, and the throughput of three tcp connection transmissions is increased by 6.5% compared with the transmission of one tcp connection. In terms of network time consumption (consumer processing time minus provider processing time), 1 tcp connection per call on the network takes an average of 9.84ms, and 2 tcp or 3 tcp connections are called each time in the network. The average time spent on it is only 0.41ms.
   
   We can see that in the case of concurrent 300 calls, the throughput of three tcp connection transmissions is 16.1% higher than that of one tcp connection transmission! ! This is an amazing number.
