Milvus java sdk is too slow for the first call

[cxxzc]

Hello,

Currently I am trying to use milvus java sdk to search, but I found that the first time cost is nearly 1s, but after changing the search vector for the second time, the time-consuming is significantly reduced. Is there any way to preheat?

1：searchTopK end.cost = 00:00:00.778； 2：searchTopK end.cost = 00:00:00.124； 3：searchTopK end.cost = 00:00:00.100; 4：searchTopK end.cost = 00:00:00.071
