We have put a large list in double quotes and used "read" to convert the large literal string (too big for hugs, though) into the needed list. This reduced compile time drastically, but I don't know how the runtime changed. (Also errors can only occur at runtime.) Christian Ketil Malde wrote:
Hi,
I've recently tried to compile some data into my program, and suddenly I realize why people tend to complain about the speed of GHC.
For a benchmark, I'd like to include a bit of data in the form of a list of integer matrices (i.e. [[[Int]]]). While I have about 10000 of them, sized about twenty square, even 100 of them takes extremely long to compile. Is there a trick to make this faster?
(For short lists (1-8 matrices), time seems to scale linarly, but the 100-matrix took much longer than expected from a simple extrapolation)
Also, it takes a long time before any error is produced, it'd be nice if syntactical problems were reported as quickly as possible (perhaps they are?)
