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. Stef
