Only thing that can be removed is a non-loading require. Is it that frequent that it had significant performance impact (given that with opcode caching non-loading require is pretty much a couple of hash lookups)? -- Stanislav Malyshev, Software Architect SugarCRM: http://www.sugarcrm.com/ (408)454-6900 ext. 227
