Hi again,
Another String performance issue. Tested on a text file with 4360 lines (\n)
(different from the one I used with other tests). With these tests, 0.9
nightly is much much slower than 0.8, so I'll file a ticket for 0.9.
Test 1 - File.read("test.txt").split(/\n/)
Test 2 - File.read("test.txt").split("\n")
Test 1 - force_encoding -
File.read("test.txt").force_encoding("UTF-16BE").split(/\n/)
Test 2 - force_encoding -
File.read("test.txt").force_encoding("UTF-16BE").split("\n".force_encoding("UTF-16BE"))
Test 3 - File.read("test.txt").lines {}
