Never have used memcached, but looks straight forward enough. It is interesting to me that there really is no free lunch. If your database machine is not fast enough and you spread out the load to memcached, you then need a very fast network. and so forth. "A single instance of memcached was run on a SunFire X2270 (2 socket Nehalem) with 48GB of memory and an Oplin 10G card. Several external client systems were used to drive load against the server using an internally developed Memcached benchmark. More on the benchmark later.
The clients connected to the server using a single 10 Gigabit Ethernet link. At the maximum throughput of 350K, the network was about 52% utilized and the server was 62% utilized. " Memcached Performance on Sun's Nehalem System (Submitted by Noel Tue Apr 21, 2009 ) |
