Why was the VW parser slower?
what kind of optimizations did you use?
The intermediate literal array falls away, now its
Text -> Parser -> some logic -> model objects
using Smalltalk parser its
Text -> Parser -> intermediate array -> some logic -> model objects
I guess Lukas's parser is the fastest you can get
Unless you are "crazy" enough to do manual tweakings :D Which is not
even sure to speed up the process anyway...
Apparently this is no what I understood from the first
mse format.
Adrian's first implementation used a literal array representation
just to avoid to do the -TRUE- to true kind of conversion. Adrian
can
you comment on that?
The first prototype re-used the Smalltalk parser, right. Now we use a
custom scanner / parser as this is faster.
