Hi Eliot.
squeak:
ping: three hundred thirty-two million elements. Time: 0:01:17:52.1782318978202152
pharo:
ping: three hundred thirty-two million elements. Time: 0:02:04:23.8802
I ran on the correct image this time and for the full SAX parse of 32 million.
Here are the "out of the box" VM stats:
uptime 3m 48s (runtime 0m 43s, idletime 3m 5s)
memory 128,974,848 bytes
old 120,022,816 bytes (93.1%)
young 7,190,528 bytes (5.6%)
used 97,823,320 bytes (75.8%)
free 27,227,304 bytes (21.1%)
GCs 126 (1811.3 ms between GCs 342.7 ms runtime between GCs)
full 4 totalling 273 ms (0.63% runtime), avg 68.3 ms
marking 129 ms (47.3%) avg 32.3 ms,
compacting 144 ms (52.7%) avg 36 ms
scavenges 122 totalling 57 ms (0.13% runtime), avg 0.5 ms
tenures 92,778 (avg 760 tenures per scavenge)
Code compactions
12 totalling 11 ms (0.025% runtime), avg 0.9 ms
Since last view 106 (1478 ms between GCs, 307 ms runtime between GCs)
uptime 156.8 s, runtime 32.6 s, idletime 124.2 s
full 3 totalling 215 ms (0.7% runtime), avg 71.7 ms
scavenge 103 totalling 47 ms (0.1% runtime), avg 0.5 ms
tenures 13,351 (avg 129 tenures per scavenge)
code compactions 12 totalling 11 ms (0.034% runtime), avg 0.9 ms
Here are the post VM stats (including the set paramater stuff you suggested earlier)
uptime 2h 22m 11s (runtime 1h 25m 59s, idletime 56m 11s)
memory 9,223,274,496 bytes
old 8,684,791,584 bytes (94.2%)
young 528,447,488 bytes (5.7%)
used -238,771,944 bytes (-2.6%)
free 8,950,420,208 bytes (97%)
GCs 936 (9114.4 ms between GCs 5511.9 ms runtime between GCs)
full 91 totalling 9,216 ms (0.18% runtime), avg 101.3 ms
marking 3,441 ms (37.3%) avg 37.8 ms,
compacting 5,775 ms (62.7%) avg 63.5 ms
scavenges 845 totalling 549 ms (0.01% runtime), avg 0.6 ms
tenures 39,912 (avg 47 tenures per scavenge)
Code compactions
91 totalling 86 ms (0.002% runtime), avg 0.9 ms
Thanks for all your hard work!
Cordially,
