If you’re using VPS solutions… unless you can predict your usage and the usage of the other tenants on the same bare metal then be sure to perform all your processing and computation as soon as possible.  There is no point in delaying the processing … if you have to delay any processing that then becomes the equivalent of a heavy batch job your system contention will change to one where the batch will never have enough or will have sporadic resources and processing profiles. Doing the processing ASAP means that the profile will be flattened as the intra transaction gap will be erased by the transactional latency.
