Date: Thu, 13 Mar 1997 13:15:02 +0900 (JST) From: Michael Hancock <michaelh@cet.co.jp> I think UnixWare has a very good AIO implementation, so reads and writes to raw partitions blaze. Solaris has this as well, and I know at least Oracle takes advantage of it. My guess is that the higher powered machine configuration in the UnixWare runs (if this were in fact the case) contributed to the better numbers. It's all disk IO and a blaze of fast TCP transactions. ---------------------------------------------//// Yow! 11.26 MB/s remote host TCP bandwidth & //// 199 usec remote TCP latency over 100Mb/s //// ethernet.
