Do you mean 16 *TB* instead of 16 *GB*? If it's really 16 GB, you should check if it's cheaper to buy more RAM than to fiddle with the existing infrastructure. > however the table structure is almost identical (UTF8 on the new one > vs. C on the old). Locale settings make a huge difference for sorting and LIKE queries. We usually use the C locale and SQL_ASCII encoding, mostly for performance reasons. (Proper UTF-8 can be enforced through constraints if necessary.) -- Florian Weimer <fweimer@xxxxxx> BFK edv-consulting GmbH http://www.bfk.de/ Kriegsstraße 100 tel: +49-721-96201-1 D-76133 Karlsruhe fax: +49-721-96201-99
