Slow HTTP requests in .NET

When profiling a web application I have noticed constant delays of about 200ms on some HTTP calls it was making to an external API. Both the web application and the API were on the same network segment and thus network latency was out of the question. Besides the target API has previously been subject to jMeter load tests and proven to handle 1500req/s. What was even more peculiar in this situation was that only the POST requests were exhibiting this delay. GET requests were pretty fast as expected.
