[RFC] Machine Function Splitter - Split out cold blocks from machine functions using profile data
...eparate section. The linker groups all cold
blocks across functions together, decreasing fragmentation and improving
icache and itlb utilization. Our experiments show >2% performance
improvement on clang bootstrap, ~1% improvement on Google workloads and
1.6% mean performance improvement on SPEC IntRate 2017.
Motivation
Recent work at Google has shown that aggressive, profile-driven inlining
for performance has led to significant code bloat and icache
fragmentation (AsmDB
- Ayers et al ‘2019 <https://research.google/pubs/pub48320/>). We find that
most functions 5 KiB or larger have inlined...

serious networking (em) performance (ggate and NFS) problem
Dear best guys,
I really love 5.3 in many ways but here're some unbelievable transfer rates,
after I went out and bought a pair of Intel GigaBit Ethernet Cards to solve
my performance problem (*laugh*):
(In short, see *** below)
Tests were done with two Intel GigaBit Ethernet cards (82547EI, 32bit PCI
Desktop adapter MT) connected directly without a switch/hub and "device
