about slowdown between 38 and 39

hi lukas

have you noticed a real slowdown between 3.8 and 3.9?
For my small comix application when I load and run the same version

In 3.8 full I reloaded from scratch everything from Pier 1.0.9
                Magritte-Model 242
                Magritte-Seaside 214
                XML-Parser 3
                Time millisecondsToRun: [ | bdb |
                        BDBase initialize.
                        BDBase resetBaseNamed: #BD.
                        bdb := BDBase new name: #BD.
                        bdb importMostRecentXML.] 1677

In 3.9 full reloaded from scratch everything from Pier 1.0.9
                Magritte-Model 242
                Magritte-Seaside 214
                XML-Parser 3
                Time millisecondsToRun: [ | bdb |
                        BDBase initialize.
                        BDBase resetBaseNamed: #BD.
                        bdb := BDBase new name: #BD.
                        bdb importMostRecentXML.] 21151

The import is basically using magritte and domparser.

I will run messageTally to see if I get some idea.

That's odd. Usually I found Squeak 3.9 much faster. Magnitudes faster.

Yes, it would be interesting to compare the traces. Maybe the parser  
does something special in 3.9? Pier and Magritte use exactly the same  
code in both versions.

Cheers,
