It would’ve been nice if the filename contained some useful information like date, camera model, maybe even location. MaxProcs set to a quarter the number of CPUs on the current system (minimallyġ) no more than maxProcs instances of exiftool will be spawned.Recently I exported a whole bunch of files from Lightroom to a NAS share and filenames like 2E570434-67B7E0489CA2-39354-000017CF24DD8ACD.jpg are not very informative. To avoid overwhelming your system, the exiftool singleton is configured with a Instance of ExifTool across many requests, dropping response latencyĭramatically as well as reducing system load. Using ExifTool's -stay_open batch mode means we can reuse a single SSD can process 20+ files per second per thread, or 500+ files per second when Hierarchy of sample images and videos, and parses the results.Įxiftool-vendored v16.0.0 on a 2019 AMD Ryzen 3900X running Ubuntu 20.04 on an path/to/examples target reads all tags found in a directory
On a performant linux box, a smaller value of streamFlushMillis may work as The default exiftool singleton is intentionally throttled. stringify ( tags ) // parseJSON doesn't validate the input, so we don't assert that it's a Tags // instance, but you can cast it (unsafely.) const tags2: Tags = parseJSON ( str ) as Tags Performance readTags ( "/path/to/file.jpg" ) const str: string = JSON.

Note that if you don't use the default singleton, you don't need to. Those defaults have been used to create the There are many configuration options to ExifTool, but all values have (more or Validating your own systems, but don't be surprised when everything still works.
