<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>It's really depends on what your pod did.
As @spencer mentioned. Besides that, there still many factor will impact your expectation：</p>
<ol>
<li>Does your pod has leader election?</li>
<li>QPS/Burst setting(for controller,since I have no idea what your pod did).</li>
<li>...</li>
</ol>
<p>Based on your case, I guess your pod is not the TPS limiting factor.</p>
<p>Basically increase the replication of pod will not low down the TPS at least.</p>
