体型 配置： [ MOVE ]

测试只数 ：500只
出兵速度：30tick出一次（如果spawn被占用则不生）
路上被杀了 1 只（没能走到最后的） ,房间在：s2的 [E30N40] 相当于index 23

cpu分配情况：s0，s1不分配，s2，s3cpu充足

结果：

s0
index3:490
index4:490
index6:484
index7:484
index8:484
index10:480
index11:480
index13:472
index14:472
index16:464
index17:464
index19:457
index20:457
index21:457

s1
index2:492
index5:486
index9:480
index12:476
index15:470
index18:459
index22:454

s2
index1:494
index23:451

s3
index0:500
index24:448 

观察可得出：在跨shard的时候有概率出现丢失的现象，是同shard的不丢creep
具体数据如下：

index1:494
index2:492
index3:490
index5:486
index6:484
index9:480
index10:480
index12:476
index13:472
index15:470
index16:464
index18:459
index19:457
index22:454
index23:451
index24:448（最后应该为 449 ，死掉的那只）

得出跨16次shard大约丢了 10% 的creep，
假设每次不丢creep的概率为 P
有 Math.pow(P,16) = 0.9
P 约为 0.993
所以跨一次 shard 丢爬的概率为 1 - 0.993 = 0.007= 0.7%

这里仅仅是估算，具体得看实际服务器的波动情况
