當榛子投上時，性能下降。當榛子投上時，性能下降
我是新來的榛樹服務，需要一些幫助。希望專家們在這裏做出一些迴應。
對象引用，當客戶端命中平靜的服務時，HTTP調用的響應速度減慢400％（2秒），如下圖所示。 https://drive.google.com/open?id=0ByIpkcJW-nHLVHJWRzJkOHFPdkE
如果hazelcast之一是關閉的，響應速度快（500毫秒）
有3K左右的結果從HTTP REST的服務調用返回。
設置上的任何建議可以解決性能問題？或者安裝有問題
以下是關於寧靜服務的其他信息。

While recovering from split-brain (network partitioning),
map entries in the small cluster will merge into the bigger cluster

cluster, there might an existing entry with the same key already.

Which value should be set for the key? Conflict is resolved by
the policy set here. Default policy is PutIfAbsentMapMergePolicy
There are built-in merge policies such as
com.hazelcast.map.merge.PassThroughMergePolicy; entry will be overwritten if merging entry exists for the key.
com.hazelcast.map.merge.PutIfAbsentMapMergePolicy ; entry will be added if the merging entry doesn't exist in the cluster.

當您使用兩個不同Hazelcast情況下，他們使用的數據備份爲默認值。如果您正在向Hazelcast寫入一些數據，可能會增加花費在請求上的時間。如果數據被刪除並重復添加到Hazelcast，它也可能導致此問題。 此外，[這裏] [1]是您如何編輯備份配置： [1]：http://docs.hazelcast.org/docs/latest-development/manual/html/Distributed_Data_Structures/ Map/Backing_Up_Maps.html – ahmetcetin
如果您運行的是少於或等於兩個實例，則可以在Hazelcast的mancenter中檢查備份。 – ahmetcetin
hi @ahmetcetin，當沒有數據被寫入/刪除時，性能是一樣的慢，因爲默認會影響花費的時間。 –
