I've asked mysql to log queries not using indexes, and ended adding a couple of indexes on a table or two. One of the SELECTs used by PNP was not using any index at all. I was tempted to add an index on all "datetime" fields but it would be overkill :) Now mysql outputs no warning (and no slow queries) but my test instance is too smalll... Time for me to monitor everything twice and see what happens :) -- seb ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
