Information processing apparatus for data writing and computer-readable recording medium having stored therein control program

A non-transitory computer-readable recording medium having stored therein a control program for causing a computer to execute a process comprising:

• obtaining, when an operating system detects a first writing process writing first data into a region in a process space in which region a file stored in a storage is mapped, a first data size of the first data from recording information recording a data size of writing target data for a target address for each of a plurality of writing processes, the first writing process being one of the plurality of writing processes that an application executes;
• reading, when the first data size is less than a first threshold, a second data corresponding to the first data and having a second data size larger than the first data size from the file stored in the storage into a memory;
• and
• rewriting part of the second data stored in a writing region of the second data in the memory with the first data;
• and
• writing third data in the writing region in the memory into the file stored in the storage, the third data being a result of rewriting the part of the second data with the first data.
