Hi all,

Today I deleted 25,000 records from a 30,000 record table, and packed it. A SQL (40 records) which had been taking <1 sec. now took 15 sec.
:-(((
So, I:

a. reindexed. Still slow

b. re-packed Still slow

c. checked every clause in the SQL and matched them with indexes. Still slow

d. Restored the original. Speed was fine. :-))

e. Deleted, speed was fine. :-)

f. Packed - slow again :-((

g. Copied data (5K records) to a temp file, ZAPped and appended.

Speed is now terrific - almost too fast to see. :-)

Question: Why did this happen?

TIA
Barbara
