Amazingly enough Kai Schulte said: > Really 486? Don't the -m486 alignments bloat the code unnecessarily?
Well, if using more memory results in faster memory accesses, is it unnecessary? The alignments result in faster code accesses. But if you have limited core, perhaps the compact code is more appropriate.
However, since the 486 compiled kernels will no longer work on 386 machines, I'm assuming the kernel can take advantage of some of the 486+ enhancements (mostly associated with context switching I think?) These enhancements may offset even the extra swapping that will occur.
Does anyone have any info on memory usage of 386 v 486 v pent compile kernels, for same config?
