Nothing the this one's PCI slot. Realtek USB 10/100/1000 LAN via using https://reviews.freebsd.org/D25809 . Serial console. SATA SSD. FYI: Its -j4 buildworld buildkernel results are somewhat slower than for an OverDrive 1000. (Similarly for poudriere bulk runs. Single threaded activity is a different story.) Builds are CPU/memory bound, not I/O bound, for both systems. ENVIRONMENT: -mcpu=cortex-a57 OverDrive 1000 @1.7G Hz, 8 GiByte RAM total (2 DIMMs slots, both populated): World built in 15508 seconds, ncpu: 4, make -j4 Kernel(s) GENERIC-NODBG built in 1117 seconds, ncpu: 4, make -j4 ENVIRONMENT: -mcpu=cortex-a72 MACCHIATObin Double Shot @ 2G Hz, 16 GiByte RAM (1 DIMM slot): World built in 18789 seconds, ncpu: 4, make -j4 Kernel(s) GENERIC-NODBG built in 1296 seconds, ncpu: 4, make -j4 The only differences in my equivalents of src.conf are the 57's vs. 72's in -mcpu= usage (same arch different tuning). head -r363590 doing self-hosted, from-scratch rebuilds. What contributes? L0-L2 cache size differences and dual DIMM (dual channel? interleaving?) vs. single DIMM. Cache performance for 4 active threads keeps the two systems similarly performant for problems that fit in both sizes of RAM cache. But the OverDrive looks to have 4 times the RAM cache. That matters for -j4 buildworld buildkernel . [The .png (that will not make it to the list) is a graph of benchmark data from my C++17 variant of some old HINT benchmarks. Data types: d=double, ull=unsigned long long, ul=unsigned long, ui=unsigned int. In this context, variations in ull vs. ul results for a given system give a clue as to the degree of other sources of variability: both are 64-bit unsigned here. Y-axis: larger is faster. While gcc10 was used, the system libc++ and such were used instead of gcc's libraries.] === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar) _______________________________________________ freebsd-ports@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "freebsd-ports-unsubscr...@freebsd.org"
