Related to change 18278[1], I was wondering if there is really a benefit of
dealing with 128-byte cachelines like we do today.
Compiling VPP with cacheline size set to 128 will basically just add 64 bytes
of unused space at the end of each cacheline so
vlib_buffer_t for example will grow from 1
Related to change 18278[1], I was wondering if there is really a benefit of
dealing with 128-byte cachelines like we do today.
Compiling VPP with cacheline size set to 128 will basically just add 64 bytes
of unused space at the end of each cacheline so
vlib_buffer_t for example will grow from 12
