This section shows a slightly longer example of asynchronous I/O processing. The running sample is an application that must read a large number of image files and perform some processing on them. This kind of application may be compute bound (if the processing takes a long time and the file system is fast) or I/O bound (if the processing is quick and the file system is slow). Using asynchronous techniques tends to give good overall performance gains when an application is I/O bound and can also give performance improvements for compute-bound applications if asynchronous operations are executed in parallel on multicore machines. Listing 13-6 shows a synchronous implementation of the image-transformation program. Listing 13-6. A Synchronous Image Processor open System.IO let numImages = 200 let size = 512 let numPixels = size * size let makeImageFiles () = printfn "making %d %dx%d images... " numImages size size

Spawn server;; val it : unit = () > http "http://127001:8090/iisstarthtm";; val it : string = ".." // the text of the iisstarthtm file will be shown here This HTTP request (or you can also open the previous URL in a browser) ultimately sends the following text down the TCP socket connection: GET iisstarthtm HTTP/11 When started, the server in Listing 14-1 attaches itself to a given port (8090) on the local machine (which has IP 127001) and listens for incoming requests These requests are line-based, so when one comes in, we read the full input line and attempt to parse a valid GET request using regular expression matching Other commands and error recovery are not dealt with.
