--- Begin Message ---Package: dh-strip-nondeterminism Version: 0.034-1 I noticed that Debian's clojure-1.8.0.jar had terrible performance as compared to both the upstream jar and one built manually via the "mvn package" or ant process, and after some investigation, I think I've tracked it down to dh-strip-nondeterminism. Given the current clojure 1.8.0-2 source tree, adding this to debian/rules: # Ask clojure to do nothing define timeclj time java -cp debian/libclojure-java/usr/share/java/clojure-1.8.0.jar \ clojure.main -e '' endef override_dh_strip_nondeterminism: $(timeclj) dh_strip_nondeterminism $(timeclj) and then running "fakeroot debian/rules binary" produces this: time java -cp debian/libclojure-java/usr/share/java/clojure-1.8.0.jar clojure.main -e '' real 0m0.919s user 0m1.739s sys 0m0.064s dh_strip_nondeterminism time java -cp debian/libclojure-java/usr/share/java/clojure-1.8.0.jar clojure.main -e '' real 0m4.064s user 0m12.204s sys 0m0.140s Thanks -- Rob Browning rlb @defaultvalue.org and @debian.org GPG as of 2011-07-10 E6A9 DA3C C9FD 1FF8 C676 D2C4 C0F0 39E9 ED1B 597A GPG as of 2002-11-03 14DD 432F AE39 534D B592 F9A0 25C8 D377 8C7E 73A4

It looks like maybe I hadn't actually pulled in the latest clojure1.8 when I upgraded, but that doesn't explain why my local build was also slow and I think had the homogeneous timestamps... But I can verify that clojure1.8 1.8.0-6 seems fine now: $ dpkg --status clojure1.8 | grep Version Version: 1.8.0-6 $ dlocate /usr/bin/clojure1.8 clojure1.8: /usr/bin/clojure1.8 $ time clojure1.8 -e '' real 0m0.852s user 0m1.640s sys 0m0.063s $ jar -tvf /usr/share/maven-repo/org/clojure/clojure/1.8.0/clojure-1.8.0.jar | grep -E 'clojure/core(\.clj|\$interleave)' 580 Sun Jun 24 23:02:08 CDT 2018 clojure/core$interleave$fn__5149.class 1138 Sun Jun 24 23:02:08 CDT 2018 clojure/core$interleave$fn__5151.class 1740 Sun Jun 24 23:02:08 CDT 2018 clojure/core$interleave$fn__5154.class 1826 Sun Jun 24 23:02:08 CDT 2018 clojure/core$interleave.class 251643 Sun Jun 24 23:02:06 CDT 2018 clojure/core.clj And I see the expected timestamps for the current sid clojure1.9 (via clojure) too: $ dpkg --status clojure | grep Version Version: 1.9.0-4 $ jar -tvf /usr/share/maven-repo/org/clojure/clojure/1.9.0/clojure-1.9.0.jar | grep -E 'clojure/core(\.clj|\$interleave)' 580 Sun Jun 24 23:56:18 CDT 2018 clojure/core$interleave$fn__8515.class 1140 Sun Jun 24 23:56:18 CDT 2018 clojure/core$interleave$fn__8517.class 1742 Sun Jun 24 23:56:18 CDT 2018 clojure/core$interleave$fn__8520.class 1826 Sun Jun 24 23:56:18 CDT 2018 clojure/core$interleave.class 259697 Sun Jun 24 23:56:16 CDT 2018 clojure/core.clj But I do see a ~3x slowdown for 1.9 as compared to a locally built uberjar: $ clj-local Clojure 1.9.0 user=> $ time clj-local -e '' real 0m0.675s user 0m1.108s sys 0m0.075s $ time java -cp /usr/share/maven-repo/org/clojure/clojure/1.9.0/clojure-1.9.0.jar clojure.main -e '' real 0m2.252s user 0m5.976s sys 0m0.111s In any case, at the moment I don't have any reason to think that's timestamp-related, as compared to anything else, so I'll (re)close this for now.
