Hello Mike;
Expiring timestamps MIGHT be kicking off an ugly series of fetches
by global id (i.e. a bunch of single object fetches).
This is my point –– I reduce the lag which ought to create more SQL
to be executed, but this extra SQL *appears* to be faster than only
looking up the snapshots in the virtual machine (for the
circumstances I'm considering) which I would expect to be occurring
in both cases on the same volume of in-memory data anyway. I
understand the end result and how it is derived, but I don't
understand the difference in time taken to get the final result. I
might just leave it at that though -- this discussion has been very
useful.
cheers.
