Too much of the system’s work seemed to be regularly swapped to virtual memory swap (SSD), a condition generally to be avoided.
The change in memory capacity and process configuration seems to have made the blogs a bit more responsive. However, it appears that most of the slow rendering I’ve noted relates more to Safari behaviour with the content of the site than with any shortcomings of my server hardware.
