I should clarify that the b-tree is a code that noone wants to touch at this point of time (not generally) such a short time before the feature freeze with low resources on the team and so many other tasks with a higher priority, with uncertain (performance) outcomes of such a rewrite. I am not sure why this is a defect. At this point it seems to me more like a hypothesis (RFE/TASK?). Note: By using mmap instead of RandomAccessFile, you also save a file descriptor (at least on linux), so you won't run out of them on large number of opened projects (like nbbuild/misc). We prototyped usage of java.nio by the b-tree and decided to not switch. See issue 50085 for more info. |
