2.4 does not reload CR3, unless you are using multiple user-space processes.

as i told you in the previous mail, the main overhead is not CR3, it's the copying & dirtying of all data, and the subsequent DMA-initiated dirty cacheline writeback. I can serve 100 MB/sec web content with 2.4 & TUX just fine - it relies on a zero-copying infrastructure.
