best index method for heavy update and read table
Pushpa Kumara (Informix 11.70) asked for the best indexing approach for a table with heavy updates and reads, which had separate single-column indexes on several columns and was slow. Art Kagel asked what was slow, then asked for set explain output for typical queries, updates and inserts. Pushpa said updates, inserts and selects were all slow. No solution in the thread.
