    - Most metric name checks in the procstat parser now use plain C string
        matching instead of regular expressions
    - Overhead has been reduced to 1.09% for a full vmstat + meminfo +
        procstat instantiation on a CoolMUC3 node (2700+ metrics each sec)
    - Overhead for a minimal meminfo instantiation is 0.05% (44 metrics)
    - We can safely assume linear scaling of the plugin in function of the
        number of metrics
