当进行淡褐色铸造时性能下降。
我是hazelcast服务的新手，需要一些帮助。希望来自专家的一些回复。
主题是指，当客户端点击下图中的restful服务时，HTTP调用的响应缓慢400％（2秒）。 https://drive.google.com/open?id=0ByIpkcJW-nHLVHJWRzJkOHFPdkE
如果其中一个淡褐色播出，则响应速度更快（500毫秒）
HTTP restful services调用返回大约3k的结果。
有关可解决性能问题的设置的任何建议？或者设置有问题
以下是有关其余服务的其他信息。

Which value should be set for the key? Conflict is resolved by

提高绩效的几点建议
答案 2 :(得分：0)
使用Hazelcast 3.9时，我们发现了严重的性能问题。升级到hazelcast 3.11.4版后，性能得到了显着改善。
