Optimizing an Operating System I/O Operation that Pertains to a Specific Program and File

In a data processing system that includes an operating system, one or more program components running on the operating system, and a file system associated with one or more files, a method comprising the steps of:

• responsive to a given write request sent from a specified program component to the operating system, in order to write specified data content to a given file, determining whether the given write request meets a criterion, wherein said criterion is derived from the identity of at least one of the specified program component and the given file;
• responsive to determining that the given write request meets said criterion, immediately sending a message to release the specified program component from a wait state;
• selectively writing data portions of the specified data content to a storage buffer;
• and
• subsequently writing each data portion from the storage buffer to the given file.
