	Has anyone noticed that the time to invoke ingres
	is much more the first time after a compilation (of an equel 
	program) than the subsequent ones? That is, if the
	same compiled equel program is executed two or more
	times, the time taken to log in to ingres is longer the
	first time than the subsequent executions. Any possible
	reasons for this? By the way, the version of ingres used
	was AT&T INGRES.

RTI INGRES has a method of storeing query plans in equel programs.
I'm not sure but perhaps the database is conditioned or these
plans are stored durring execution.

I've not heard of AT&T INGRES.  Is it not an RTI port?
