  • > ----- First off, this sentence is bogus. The comma before by is wrong. It really should be more than one sentence anyway: Also, soft updates as an entity is sinuglar, not plural. It's one specific algorithm. Soft Updates allows improved file system performance without sacrificing safety and reliability. It analyzes meta-data filesystem operations to avoid having to perform all of those operations synchronously. Instead, it maintains internal state about pending meta-data operations and uses this information to cache meta-data, rewrite meta-data operations to combine subsequent operations on the same files, and reorder meta-data operations so that they may be processed more efficiently. Does that help? The trick is that "rewrite or reorder" is one entity along with "cache" and "analyze", but it doesn't read well as you point out. :) -- John Baldwin <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-doc" in the body of the message
