As an aside, in some standard benchmark tests I run with our product, I have found the final optimisation of Lucene indexes after all the data has been indexed took 36 seconds with NIO, but 148 seconds with NIO+DirectIO enabled. For mmap, optimisation took 30 seconds but 100 seconds with DirectIO was enabled. So it is odd the use-case DirectIO was meant to speed up actually seemed to be slower.. -- This is an automated message from the Apache Git Service.
