Hi Team, While merging blink commit in bug 250640 as PR below: https://github.com/WebKit/WebKit/pull/10888 Darin's suggested that we should look for future optimization as Blink's comment mentioned to remove 'semi-colon' storage in array: # Reuse substrings from earlier entries. This saves 1-2000 # characters, but it's O(n^2) and not very smart. The optimal # solution has to solve the "Shortest Common Superstring" problem # and that is NP-Complete or worse. # # This would be even more efficient if we didn't store the # semi-colon in the array but as a bit in the entry. __________ I am just creating this to explore it in future to fix this bug as well. If someone can guide, I am happy to look into it and if someone else can grab and do it quickly. I am happy as well. _________ Darin's comment for safe-keeping: '''This is a very good point. It would be useful to continue with this optimization and remove the semicolons from the array. I am almost certain this could be done with no performance impact.''' ___________ Just wanted to raise this bug. Thanks!
