Please post your exact table schema using SHOW CREATE TABLE, and your
exact query, along with an EXPLAIN SELECT for the query.
Thanks!

Hy Guys,
I have a simple structure of tables, howewer has 50 million of registers and
2,5 GB of data.
The table is MyIsam and has 4 integer fields and 1 Text field, one primary key with two integer fields
and one btree index with one integer field.
There is a select in this table using an index(with one integer field), whith a set value
for this field ( select * from table where field in (value1,value2,value3,value4,etc) ).
This select has delay 4s average.
Is this a good time for the select ? How can I run this select in less time?
I had make this optimization:
1-Compress the index
2-sort the index with myisamchk
PS.: This table is read-only, hasn't an insert, update or delete.
