The issue is while using near-cache scheme model the data stored in the local cache is expiring and every time the request comes from client, the data is pulled from backend cache, which is causing the latency.

Issue only seen with .Net clients and not with Java Clients. .Net clients using Near Cache whereas Java Clients not using Near-Cache. The cache size is also limited. Customer claims that the Synthetic events set to true has increased a lot due to more evictions. Client requests coming at normal rate.
