As promised, here are more results running memcached on Sun's X2270 (Nehalem-based server). In my previous post, I mentioned that we got 350K ops/sec running a single instance of memcached at which point the throughput was hampered by the scalability issues of memcached. So we ran two instances of memcached on the same server, each using 15GB of memory and tested both 1.2.5 and 1.3.2 versions. Here are the results :

The maximum throughput was 470K ops/sec using 4 threads in memcached 1.3.2. Performance of 1.2.5 was just very slightly lower. At this throughput, the network capacity of the single 10gbe card was reached as the benchmark does a lot of small packet transfers. See my earlier post for a description of the server configuration and the benchmark. At the maximum …

Memcached is the de-facto distributed caching server used to scale many web2.0 sites today. With the requirement to support a very large number of users as sites grow, memcached aids scalability by effectively cutting down on MySQL traffic and improving response times.

Memcached is a very light-weight server but is known not to scale beyond 4-6 threads. Some scalability improvements have gone into the 1.3 release (still in beta). With the new Intel Nehalem based systems improved hyper-threading providing twice as much performance as current systems, we were curious to see how memcached would perform on these systems. So we ran some tests, the results of which are shown below :

memcached 1.3.2 does scale slightly better than 1.2.5 after 4 threads. However, both versions reach their …

I introduced Olio a little while ago as a toolkit to help web developers and deployers as well as performance/operations engineers. Olio includes a web2.0 application as well as the necessary software required to drive load against it. Today, we are showcasing the first major deployment of Olio on Sun's newest Intel Nehalem based systems - the SunFire X2270 and the SunFire X4270. We tested 10,000 concurrent users (with a database of 1 million users) using over 1TB of storage in the unstructured object store.

The diagram below shows the configuration we tested.
