# Performance

Some users have noticed that current versions of OCRmyPDF do not run as
quickly as some older versions (specifically 6.x and older). This is
because OCRmyPDF added image optimization as a postprocessing step, and
it is enabled by default.

## Speed

If running OCRmyPDF quickly is your main goal, you can use settings such
as:

-   `--optimize 0` to disable file size optimization
-   `--output-type pdf` to disable PDF/A generation
-   `--fast-web-view 999999` to disable fast web view optimization
-   `--skip-big` to skip large images, if some pages have large images

You can also avoid:

-   `--force-ocr`
-   Image preprocessing
