| Summary | 0001505: server.c does memmove for alignment even when not required | ||||
| Description | The code should be changed to see if the struct is already aligned (pointer at a round multiple 8 bytes already; for GNUnet, we should be able to assume that 8-byte alignment is enough); if it is already aligned, we don't need to memmove it to the beginning of the buffer but can process it in-place. This feature will need to be tested thoroughly (especially to ensure that the resulting 8-byte aligned accesses are as portable as we expect them to be; such portability can only be demonstrated using the buildbot if a testcase actually triggers this). | ||||
| Additional Information | Would be nice to know if this optimization shows a detectable performance gain using some simple benchmark. | ||||
