For question no 2: Yes. oO I should say superpages , large pages or huge page support. Back to my questions: 1. Transparent Superpages was in FreeBSD for a few years. I would like to know if there is any benchmark or real world performance experience about this setting. For Linux, I have heard people having issues with the THP (transparent huge page) on Linux. 2. I have seen somewhere that superpages support was being developed in HEAD too. Any insight on it?
