Hi, I made the benchmarks with the files you provided. I have more or less the same magnitude: Version 504: 0:00:01:09.021 Version 1175: 0:00:02:37.507 However, by launching it in the time profiler (MooseModel new importFromMSEStream: (StandardFileStream readOnlyFileNamed: 'd:/ArgoUML-0-34.mse')), it takes 504: 1 min 55 1175: 4 min 25 Well there is a delta... After investigation, the standard process has almost the same duration (120 secs for prespur and 140 secs for spur). But, there is a large difference in GC time: 504: not spur **Memory** old +144,822,000 bytes young -8,293,660 bytes used +136,528,340 bytes free -104,186,788 bytes **GCs** full 1 totalling 965ms (1.0% uptime), avg 965.0ms incr 3264 totalling 42,279ms (33.0% uptime), avg 13.0ms tenures 2,497 (avg 1 GCs/tenure) root table 0 overflows 1175: spur **Memory** old +0 bytes young +340,048 bytes used +340,048 bytes free -340,048 bytes **GCs** full 7 totalling 145,003ms (66.0% uptime), avg 20715.0ms incr 3288 totalling 30,912ms (14.0% uptime), avg 9.0ms tenures 7,146,505 (avg 0 GCs/tenure) root table 0 overflows Total GC time 504: 43 secs 1175: 176 secs See the performance reports attached. I let VM people take care of the issue ;) Cheers, Vincent -----Original Message----- From: moose-dev-bounces(a)list.inf.unibe.ch [mailto:moose-dev-bounces@list.inf.unibe.ch] On Behalf Of Tudor Girba Sent: dimanche 24 janvier 2016 09:08 To: Moose-related development Subject: [Moose-dev] Re: mse loading looks slower :( Hi, I am talking about the difference between Moose 6 images: - October 7: https://ci.inria.fr/moose/job/moose-6.0/504/artifact/moose-6.0.zip - yesterday: https://ci.inria.fr/moose/job/moose-6.0/1175/artifact/moose-6.0.zip Multiple things did change, but not in Moose. In the end, I would like to understand where the slowness comes. Maybe it comes from Spur itself, but maybe it comes from somewhere else. Cheers, Doru wrote: before and after Spur, do you mean a Pharo 5.0 exactly (just before Spur) and a Pharo JUST after it? Otherwise, the slowness may come from the difference between the 2 Pharos you are running. twice as slow with Spur than before: readOnlyFileNamed: 'ArgoUML-0-34' / 'ArgoUML-0-34.mse') fullName). -- www.tudorgirba.com www.feenk.com "What is more important: To be happy, or to make happy?" _______________________________________________ Moose-dev mailing list Moose-dev(a)list.inf.unibe.ch https://www.list.inf.unibe.ch/listinfo/moose-dev
