IF you take a 1.1 core and just load OCompletion:
MessageTally time: [ECContextTest new testUntypedVarsOnly] 20907
If you load OCompletion and the rest of the dev image:
MessageTally time: [ECContextTest new testUntypedVarsOnly] 100137
However, IN pharo dev 1.0 it is
MessageTally time: [ECContextTest new testUntypedVarsOnly] 7405
sooo.... ????
something has changed?
As I said, SortedCollection is not suitable for this kind of usage.
But in Pharo 1.0 OCompletion was doing the same....so? did
SortedCollection
chang between 1.0 and 1.1?
No, something else changed. The same test is still 5x faster in 1.0
dev with the new code.
TimeProfiler to the rescue:
Preferences class >> ecompletionCaseSensitive
1.0: (1725ms)
1.1 (19724ms)
Preference>>settingValue which is there for backwards-compatability in
1.1 does both symbol creation and respondsTo:, so yeah, it's much slower
than the old dictionary lookup.
