Feels unlikely to be paging issues then. Always useful to cross items
off the list :-).
Does the app make any calls across to authentication or database systems
where the connection might have timed out overnight and need to be
re-established? Does any connection go via a firewall or router that
might have silently dropped a TCP mapping from its cache and hence the
TCP connection would have to go through its retransmission timeout (NAT
routers are beggars for this, but I doubt you're in that environment)?
Is the server's DNS or other name resolution well-configured such that
it won't encounter pauses resolving network names for resources on other
machines? Is its DNS server well-configured so that it doesn't
encounter delays resolving names for resources?
Just random thoughts, I know, but they've tripped me up at other
installations so I offer them for shooting down!
