.upload with FileDataPart is slow?

See original GitHub issue

This is for version 2.0.1 Don’t know why, but this code (serviceUrl is localhost in my case):

val response = Fuel.upload(serviceUrl/"jars"/"upload")
    .add(FileDataPart(file = fileToUpload, name = "jarfile", contentType = "application/java-archive"))
    .awaitObject(uploadJarDeserializer)

is very slow on large files (over 100 MB). When I switch to

val response = Fuel.upload(serviceUrl/"jars"/"upload")
    .add(BlobDataPart(inputStream = fileToUpload.inputStream(), name = "jarfile", filename = fileToUpload.name, contentType = "application/java-archive"))
    .awaitObject(uploadJarDeserializer)

it is very fast, as expected.

So by replacing FileDataPart to BlobDataPart - I have improved a performance in order of magnitude. Am I doing something wrong with FileDataPart?

Ugh. @mobiletoly, yes you are right. setFixedLengthStreamingMode is supposed to be faster than setChunkedStreamingMode. However, this is enough information for us to do some debugging here.

Thank you for the time ❤️

this is desktop app (TornadoFX-based app), running on my Mac, so no Android. Using BlobDataPart is very fast, using Apache HttpClient is very fast, it is only when I use FileDataPart I start having issues.
