[comp.lang.eiffel] Cognos's Eiffel experiences in ECOOP/OOPSLA 90

ted@computing-maths.cardiff.ac.uk (Ted Lawson) (12/15/90)

	About six months ago (?) there was a discussion in this newsgroup,
	initiated by Burton Leathers of Cognos, concerning Cognos's
	rather negative experiences with Eiffel, particularly in relation
	to performance of big Eiffel systems. Betrand Meyer posted a reply
	which stated that in version 2.2 the post-processor was sufficient
	to deal with the performance defects.
	
	Burton Leathers raised the Eiffel performance issue again in his
	position paper at this year's ECOOP/OOPSLA conference. Does this
	refer to pre-2.2 days or does the current Eiffel implementation
	still have serious performance defects that have yet to be recified ?

	As far as we can tell, Eiffel deficiencies reported by Mr. Burton Leathers 
	at various Conferences (SCOOP-East, SCOOP-West, SOOPPA, OOPSLA,...) 
	refer to Eiffel 2.1 (released in July 1988).

	
	Note:
		Eiffel 2.2 (1989) and 2.3 (1990) releases overviews with
		changes and improvements may be found in the following articles:
