Daniel, which db backend are you using for your tests? It can matter where the data resides. Even for temporary tables, you can end up paying the fsync() penalty of storing the data into disk (when you really don't care). > Maybe attacking those parser tests directly will solve the > database-caused performance problem for you without going through the > trouble of adding read-only Database tests? You can just run the parser tests with parserTests.php, which doesn't recreate tables and is much faster.
