...do a run with --merge-strings. This should probably the the > default to match other ELF linkers. Trying --merge-strings with today's trunk I got * comment got 77 797 bytes smaller. * rodata got 9 394 257 bytes smaller. Comparing with gold, comment now has the same size and rodata is 55 021 bytes bigger. Amusingly, merging strings seems to make lld a bit faster. With today's files I got: lld: --------------------------------------------------------------------------- 1985.256427 task-clock (msec) # 0.999 CPUs utilized ( +- 0.07% )...

...D performance and just wanted to share things what I found. Also if there's anyone who have a good idea on how to make it faster, I'd like to hear. My focus is mainly on Windows, but my optimizations are generally platform neutral. I aim both single-thread and multi-thread performance. r231434 <http://reviews.llvm.org/rL231454> is a change that has the largest impact. It greatly reduced linking time to link large binaries, as it changed the order of number of symbols we need to process for files within --start-group/--end-group. If you have many library files in a group, you wou...

...ied that servers can advertise block size limitations to clients that ask with NBD_OPT_GO (although we're still a ways off from implementing that in nbdkit); and that in the absence of that, then clients should agree on limits using out-of-band information or stick to sane defaults (everything 512-byte-aligned, no reads or writes larger than 32M). But the protocol is not inherently prevented from serving 1-byte requests, nor does it prohibit a request of nearly 4G on bulk actions like trim and zero; and nbdkit itself supports 1-byte requests, read and write up to 64M, and no limit on trim...

Hi, At the n2k10 OpenBSD network hackathon, I finally got some time to clean up and rewrite the ssh(1) client multiplexing code. The attached diffs (one for portable OpenSSH, one for OpenBSD) are the result, and they need some testing. The revised multiplexing code uses a better protocol between the master and sl...

This is the previous 5/9 patch posted earlier today, split into reviewable chunks. This passes bisection with -x 'make && make check', but I didn't work very hard on the commit messages, so I refer you back to the original patch to explain how it works: https://www.redhat.com/archives/libguestfs/2020-March/msg00248.html Rich.
