--- Comment #40 from Michael Meeks <[email protected]> --- I guess improving the spreadsheet to match at the beginning of the string is not feasible ? =) it is doing a -ton- of un-necessary work left & right in there. I can't see us downgrading ICU really. Beyond that if someone wants to investigate that - they need to generate a matched pair of callgrind traces for the same workload (with symbols) for the older (faster) version, and the newer (slower) version - and see if indeed the problem is with ICU. If so, we then would want to write a micro-benchmark of that, and report to the ICU people and/or look at exactly what is wrong here. Failing that, there are of course, lots of potential opportunities for exotic CPU threading in the formula interpreter; we should be able to parallelize things rather nicely - for FormulaGroups with over-complicated regexp matching in-use - but that of course is an even bigger chunk of engineering work: if someone wants to do that work they can poke me for code pointers =) -- You are receiving this mail because: You are the assignee for the bug.
