Currently the non index read count is over 30K, and this is just a simle

Index reads means less record read - less I/O - faster execution.
Sure, but if these non-indexed reads occupy e.g. less than 10% of the
overall

Maybe not really a bug but something sub-optimal.
(I think standard DDL command shoud ALWAYS read via indicies in the
background.)

let speak first about the utf8
UTF8 it's just a way to encode special character like è à etc ..
for this utf8 will use combination of char upper than ascii #127
In this way, and it's not the less, UTF8 stay compatible with all
software that work with 8 bit string.
Tryed with ACS and DESC index. No change, still the same non index reads.
Do I upload my test database?

Tryed with the latest FB2.5 snapshot. It works! (It has 2 new index in
rdb$procedure_parameters)
Now I has only 92 index read. :)

Thank you!

juste one question, i thing both are the same but with is the best to

ASCII or ISO8859_1 ?
If you really do not care about collations, then OCTETS.
Stuff like UPPER, ORDER BY, etc. would not work properly anyway, so why
bother.

The encoding is a superset of ISO 8859-1, but differs from the IANA's

The main drawback, is that all the write are flush to the disk using the

This depends on your client application and not on your server. If your

why do you have so strange assumptions? You've made practical tests?
Or, if this is just a theory, what it is based on?
