Well IMO this can improve the speed as: 1. in most times the list is an ArrayList here in your codes. 2. when in original codes, each time you remove(0) it calls a `System.arraycopy`, means the array is copied `extra` times. 3. when use sublist.clear(), it actually called list.removeRange, which do only one `System.arraycopy`, thus far faster. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
