poor performance because of slow storage

I currently have some trouble because of a misconfigured storage. The
technicans are involved, but the reconfiguration will requires several days.

The main problem is a small table acting as dictionary. while column 1
is the key, a query will delivery the value of column 2. The select is
not critical, but the frequently changes to the table. Insert and delete
operations cause many i/o traffic on our storage.

Our reading applications use following sql-statement to perform a lookup:

SELECT col2
FROM my_table
WHERE col1='...'

Is there any chance to tune this table without the need to change the
reading apps? I think of a table in memory, which does not force i/o
traffic on the storage. Lost data after a crash is no important, this
table only holds current data. In half an hour the data is old.

Any ideas?

regards, markus
