Hi, We are using memcached to cache .net serialized items, as a asp .net session provider, a database cache, and to store real time data.
Now, we are using 4 server, with 40GB of data to memcached, in the same server that we run the IIS. All of these server have 48GB of RAM, and 2 processors Xeon Quad HT. These server have 2 1Gbps network interfaces, one for local (memcached) and other for internet (IIS). These servers are showing a strange network usage in the local interface. In one server we have around 60% of network usage and in the 3 others we have around 25%. All server have around 4k operations per second. Coincidence or not, the server with high load is the last server added to cluster. So the question, has memcached some kind of master server who need to coordinate the other servers or are something that could explain the high network usage in this interface? We are using the couchbase version of memcached (membase version 1.7.0, with memcached buckets) with the eniym client in .net. We appreciate any kind of information that could help. Best regards, Sergio Garcia
