All, We are implementing a memcached backed cache for one our high performance eCommerce application and we are noticing the following performance pattern during our initial performance tests. I would like to know from the group if any one has concrete data that you can share regarding the performance of memcached based implementations with different clients.
Here is our side of the story: Memcached Clients: Whalin 1.3.2, Whalin 2.0.1, Spy 2.4.2, Spy 2.2 Memcached Server: 1.2.8 1. We ran some performance tests with simple Java objects (approx 2 KB size) with the above setup and we notice that Whalin 1.3.2 is performing better than other client variants. This is contrary to our original expectation that later version of Whalin and Spy offer better performance comparing to Whalin 1.3.2. Any one else on the same boat? Or can some one explain if this is indeed what we should expect? 2. We are also noticing that our CPU spikes while performing a getMulti (about 240 objects per request, and 4 Transactions Per Second). Does any one know why this might be happening? Or is it what we should expect? thanks a lot for any insight into this. Regards,
