50 minutes worth spent @ Codemotion IT

If you're lucky enough to participate at this year's Rome's Codemotion then my Infinispan in 50 minutes presentation might be an option to consider: this is an overview of the Infinispanecosystem which focuses on what are the problems our data gridcan help you solve.
The presentation is on the 23 of March starting at 9:50 AM and contrary to its title, it lasts only for 40 minutes - but don't worry, I'll be around for entire duration of the conference so feel free to come and ping for a chat!

Participating at Miralce Open World 2012

I'll be presenting at this year's Miralce Open World with a talk on how Radargun is used for measuring Infinispan's performance. I think the topic is interesting for anyone that needs to prototype applications built using in-memory datagrids such as infinispan.
So if you are around and you are interested in this topic, or just want to say hi, then look for the guy with the Infinispan t-shirt (and my name on the badge)!

Enhanced reporting in Radargun

Thanks to Galder ZamarreƱo, Radargun is now able to report information about memory consumption, CPU and GC usage. The information is being recorded from the time the benchmark starts to the time it is completed, excluding the warmup phase. A time-based graph is then generated - but enough talking, a picture makes more than a thousands words:
The diagram below compares the memory consumption between two Infinispan versions running Radargun's Web Session Replication benchmark .
CPU information is also captured:
Note: in the above diagram the GC activity is very low and it gets blurred in the graph. In both graphs the benchmark ran for 175 seconds - not a very realistic run.

At the moment this feature is only available for local benchmarks, and can be enabled through the 'sysMonitorEnabled' attribute:
