I generally agree with Frank, but I have had one anecdotal report from a
user that they found PostGIS faster than Shape files on plain old read
operations once the concurrency cranked up.
Now, I can think of no technical reason why that might be so, and I have
never independently verified the report, but it is something that keeps
me from blanket saying "Shape files are faster for simple read
workloads" anymore.
(Maybe someone here can do a test?)

Generally speaking the shapefiles, and the spatial indexes will get
cached in RAM.
Also for separate invocations of cgi MapServer? Pardon if this is a
stupid question, but the arcane workings of computer hardware is not
my area of expertise :-)
