Hi guys I spent 3 hours looking for improvement in MC1.5. (of course I got problem when loading the code - but this can be fixed) When I could load it, it is indeed much faster. Finally And matthew nicely pointed me to his improvement. I will have a look at the specific speedup made by matthew and see if I can make that work. Now instead of extracting a speedup from that code (and looking like a thief) I would prefer that we do a task force and check MC1.6 improve it clean it if necessary. So does anybody with knowledge want to help on that topic? Stef Here is my conversation with matthew

Hi matthew

could you give me some hints abotu what I should look for? Because I loaded these two files I found on

But this is not that simple to spot changes.

I'd rather you just used MC1.5 rather than port it, but ok There are two speedups in Monticello 1.6: Scanning the class heiarchy looking for package elements is 10x faster, due to a rewrite of the scanning code. Loading is 3-6x faster, especially for large packages, due to the atomic loader. I believe you can't make much use of the second, as the atomic loader doesn't support traits yet. The rewritten scanning code is in class PackageInfo, category single-pass. To merge it into Monticello, simply call PackageInfo >> classesDo:methodsDo:displayingProgress: from MCPackage >> snapshot. Attached is a changeset of the relevant code, extracted from mc1.6. You may have to slightly modify MCPackage >> snapshot, as it contains instructions for interacting with the Orphanage, which I'm guessing your branch of Monticello does not include. -- Matthew Fulmer -- http://mtfulmer.wordpress.com/
