In turn, a lot of stuff that relies on lazy initialization (partly inside of libzypp) happens at that point in time. That's the downside of lazy (delayed) initialization: The performance cost has to be payed at a later time. It doesn't simply go away. If you have any idea what could be optimized, please tell me. The UI doesn't intentionally initialize anything it doesn't need anyway. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

https://bugzilla.novell.com/show_bug.cgi?id=302390#c4 Stefan Hundhammer changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |ASSIGNED --- Comment #4 from Stefan Hundhammer 2007-08-27 09:50:32 MST --- I checked with both 10.3-Beta2 and with 10.2-GA. 10.2-GA appears quicker, but in reality it is not. On my test machine it takes 7-8 seconds from pressing the "Details..." button in the pattern selector until you can actually do something in the package selector (Until the "solving dependencies..." busy popup is gone). 10.3-Beta2 on the other hand takes about 2 seconds from pressing "Details..." until you can work in the package selector. Granted, 10.3-Beta2 makes a more sluggish impression: It seems to take longer for the grey background to disappear (to be replaced with the package list etc.). Sometimes, that is. At other times it appears considerably quicker. This might have to do with multiprocessing (X server vs. y2base; it's a hyperthreading machine) and how the CPU load is distributed. Sometimes I don't see the "solving dependencies..." popup at all; this is when it appears to be more sluggish. Even then, the raw numbers speak a different language: It always takes ~2 seconds on my test machine. I can't find anything suspicious in the logs. Will continue to investigate. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

https://bugzilla.novell.com/show_bug.cgi?id=302390#c6 --- Comment #6 from Stefan Hundhammer 2007-08-29 08:29:41 MST --- This does not seem to be the problem: It all happens in the same second (y2logging only has full-second resolution). But I found a 3-second delay that I can't understand here: 2007-08-29 16:01:53 <1> snell(1692) [qt-pkg] YQPackageSelector.cc(YQPackageSelector):202 PackageSelector init done 2007-08-29 16:01:53 <0> snell(1692) [libycp] ExecutionEnvironment.cc(popframe):93 Pop frame 0xb4cf5f40 2007-08-29 16:01:53 <0> snell(1692) [libycp] ExecutionEnvironment.cc(pushframe):78 Push frame RunPkgSelection (`id (`packages)) [what is happening here?] 2007-08-29 16:01:56 <0> snell(1692) [qt-pkg] YQPkgConflictDialog.cc(solveAndShowConflicts):223 Solving... 2007-08-29 16:01:56 <1> snell(1692) [zypp] Resolver.cc(resolvePool):1267 pool has been CHANGED --> resetting solverresults 2007-08-29 16:01:56 <1> snell(1692) [zypp] Resolver.cc(resolvePool):1296 Resolver::resolvePool() -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

From the moment you click on the [Details...] button until the package selector is open and ready it takes less than 2 seconds (too quick for reliable manual timing with a stop watch).
