    Abstract: Exemplary methods, apparatuses, and systems include a host computer selecting a first workload of a plurality of workloads running on the host computer to be subjected to an input/output (I/O) trace. The host computer determines whether to generate the I/O trace for the first workload for a first length of time or for a second length of time. The first length of time is shorter than the second length of time. The determination is based upon runtime history for the first workload, I/O trace history for the first workload, and/or workload type of the first workload. The host computer generates the I/O trace of the first workload for the selected length of time.

    Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to control a cache. An example method includes monitoring cache lines in a cache, the cache lines storing recently written data to the cache, the recently written data corresponding to main memory, comparing a total quantity of the cache lines to a threshold that is less than a cache line storage capacity of the cache, and causing a write back of at least one of the cache lines to the main memory when a store event causes the total quantity of the cache lines to satisfy the threshold.

    Abstract: Analyzing a managed runtime cache is provided. A heap associated with a managed runtime environment, where the heap includes an N-generation cache or a plurality of objects associated with a program operating within a managed runtime environment is identified. A snapshot of the heap is produced, wherein the snapshot identifies a memory location for each object of the plurality of objects at which the object is stored. A generation of each of the plurality of objects based, at least in part, on the memory location of the object is determined. One or more suggestions based, at least in part, on the memory location of the plurality of objects is provided.

    Abstract: Provided are a computer program product, system, and method for determining server write activity levels to use to adjust write cache size. Server write activity information on server write activity to the cache is gathered. The server write activity information is processed to determine a server write activity level comprising one of multiple write activity levels indicating a level of write activity. The determined server write activity level is transmitted to a storage server having a write cache, wherein the storage server uses the determined server write activity level to determine whether to adjust a size of the storage server write cache.
