<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">We are using APIMAN for very response time critical APIs like - Upload API for uploading picture, videos etc.. to AWS S3. We don't want to upload files directly to S3 as there are
few custom authentication & auth(via Redis In-Memory DB/Cache) checks we perform via our custom plugins in APIMAN. While, our APIs run OK without APIMAN, we see response time degrading considerably with APIMAN. What could be some of the best practices we should
follow for performance tuning?<o:p></o:p></p>
