Do you experience slowness in disk write ? Any proofs like iostat/iotop output ?
DiskPageStore#isSynchronous() means something slightly different. Asynchronous means that the worker http thread will not wait for the write to the disk, i.e. the write is detached. But writes are still synchronous in the special "page-saving-thread". Additionally NIO is used - each http session opens its own FileChannel that writes to a specific file for that session.
