Performance Issues:
-
Informix IUS/UD
-
multi-threaded
-
optimizations exist for datablades (shared C libraries) if C is re-entrant
-
Parallelization of User Defined Routines (9.2)
-
Server Configuration options
-
Cos functions for SQL function extensions
-
B- Tree and R-Tree as well as Custom Indexing
-
See differences in performance based on platform
-
Daylight Datablade (day.bld)
-
Daylight toolkit and functions are not multi-threaded- running IUS/UD with
"one hand tied behind its back"
-
All code had to be re-written with proper memory management for "legacy"
code.
-
Not indexed
-
Still some merlin 'tricks' left to be implimented
