[MEDIUM] http: revert to use a swap buffer for realignment The bounce realign function was algorithmically good but as expected it was not cache-friendly. Using it with large requests caused so many cache thrashing that the function itself could drain 70% of the total CPU time for only 0.5% of the calls ! Revert back to a standard memcpy() using a specially allocated swap buffer. We're now back to 2M req/s on pipelined requests.
