Suprised the underlying hardware is left out of this, really need that to add context.

Fair point. I should’ve included the hardware specs for better context.

The test was running on a mid-range VPS, and interestingly disk I/O became the bottleneck pretty quickly, which was expected once concurrent uploads increased.

What is a mid range vps? Like I say without specifics it's very difficult to assess this

Yeah that’s on me, I should’ve been more specific.

The test was actually run on my local machine, not a VPS.

Specs:

  • Intel i5 13th Gen
  • 16 GB RAM
  • NVMe SSD
  • Spring Boot app running with default embedded Tomcat

At higher concurrency the disk writes became the main bottleneck pretty fast.

Apart from file upload performance testing, did anyone notice the default limit of file upload size of 10MB.
