solrCloud的压力测试：
上一篇文章提过使用solr3.6做的架构优化。 solr 搜索架构优化
测试的时候还没有做更大数据量的并发请求压测试，最近来了新机器，比之前更加好，但没想要把索引放内存，而是放在ssd，内存是满 足的，但使用高于线上2倍多请求的时候，响应就没有之前那么良好，有下降的趋势，即使再加多8个core顶住 ，表现还是差差的。
先看一下非分多结点的测试数据：
| 4020832 | |
| #50ms以下 | 2735841 ,68.04% |
| #50ms -100ms | 364699 ,9.07% |
| #100ms -200ms | 401903 ,10.00% |
| #200ms -300ms | 191195 ,4.76% |
| #300ms -500ms | 156065 ,3.88% |
| #500-1000 | 139782 ,3.48% |
| #1000-2000 | 20087 ,0.50% |
| #2000-3000 | 11218 ,0.28% |
| #3000-5000 | 41 ,0.00% |
| #5000-以上 | 1 ,0.00% |
基于3.6.1设计的多结点测试数据：8结点＊2 双备负载
| 响应时间 | 1122万请求 | 1184万 请求数 | 983万请求 |
| #50ms以下 | 9032936 ,80.44% | 9859400 ,83.25% | 8492507 ,86.39% |
| #50ms -100ms | 730948 ,6.51% | 816640 ,6.90% | 566203 ,5.76% |
| #100ms -200ms | 679844 ,6.05% | 751707 ,6.35% | 555547 ,5.65% |
| #200ms -300ms | 218665 ,1.95% | 198764 ,1.68% | 129092 ,1.31% |
| #300ms -500ms | 166813 ,1.49% | 104998 ,0.89% | 55841 ,0.57% |
| #500-1000 | 173188 ,1.54% | 52902 ,0.45% | 21114 ,0.21% |
| #1000-2000 | 44532 ,0.40% | 11318 ,0.10% | 268 ,0.00% |
| #2000-3000 | 180387 ,1.61% | 42332 ,0.36% | 9754 ,0.10% |
| #3000-5000 | 923 ,0.01% | 3565 ,0.03% | 2 ,0.00% |
| #5000-以上 | 428 ,0.00% | 597 ,0.01% | 0 ,0.00% |
加双倍压力测试，并且再多加4结点负载。总共是（8*3），负载看一下效果：
| 响应时间 | 总量 1970万 = | 6985110 + | 6355850 + | 6362254 |
| #50ms以下 | 13824099 ,70.16% | 4570760 ,65.44% | 4625922 ,72.78% | 4627417 ,72.73% |

当然这其中还是可以再做优化，不过再看一下solrCloud请求表现：
同样是双倍的压力请求：但却只有8*2的结点负载。cpu表现稳定，且请求响应分值更佳，暂时只测试跑一会，没跑长时间的数据。取了阶段性的数据，依然保持90%是在100ms以下，而且没有看到几个机器负载彪高的趋势 .
| 响应时间 | 2563693 | 2606345 | 2898226 |
| #50ms以下 | 2168196 ,84.57% | 2207154 ,84.68% | 2449177 ,84.51% |
| #50ms -100ms | 173866 ,6.78% | 175126 ,6.72% | 195621 ,6.75% |
| #100ms -200ms | 167391 ,6.53% | 168675 ,6.47% | 190621 ,6.58% |
| #200ms -300ms | 29169 ,1.14% | 29557 ,1.13% | 33537 ,1.16% |

| #5000-以上 | 0 ,0.00% | 0 ,0.00% | 0 ,0.00% |
暂时还没有测试并行读写的时候的性能。
