Hi,
I’m running a locator and a server on my PC, and is having 50 different clients
(different compute node on a local cloud) writing to my cache simultaneously.
Each client process would write 10MB of data and close connection. The same
client process is repeated twice (put(10MB)/close/put(10MB)/close).
Occasionally, the client would require over 100s to close the connection (I’m
timing the time elapse during each point of the client process to see where is
potential bottleneck). Does anyone know why this (extremely long connection
time) occurs?
I’m not sure if this is of any use, I see the following in the server log.

In terms of configuration of my cache. It is a simple PARTITION cache without
redundancy (I’m doing evaluation of Gemfire/Geode). On the client side, below
is the client-cache xml for reference.
<client-cache>
<pool name="MyGridPool">
<locator host="10.109.35.198" port="40401"/>
</pool>
<region name = "MyCache" refid="PROXY"/>
</client-cache>
This is my code (using C++ client).
CacheFactoryPtr cacheFactory = CacheFactory::createCacheFactory();
cacheFactory->set("grid-client", "true");
cacheFactory->set("cache-xml-file", xmlPath.c_str());
CachePtr cachePtr = cacheFactory->create();
RegionPtr regionPtr = cachePtr->getRegion(“MyCache”);
regionPtr->put( key, value );
cachePtr->close();
Thanks,
Shing
