<p>Can anyone explain to me why when running my load test on one pod it gives better TPS rather than when scaling to two pods.</p>
<p>I expected that when running the same scenario with the same configuration on 2 pods the TPS will be increased but this is not what happened.</p>
<p>Is this normal behaviour that scaling horizontal not improve the total number of requests?</p>
<p>Please note that I didn't get any failures on one pod just scaled to 2 for high availability.</p>

<p>This can happen when 2 pods race for same resource and create a bottleneck.</p>

<p>Client (web) requests can improve but the capacity for backend, sometimes middleware too (if any), needs to catch up.</p>
