YouTube: Unraveling Chrome’s Memory and Lag Spikes

The abrupt occurrence of memory and lag spikes on Chrome while using YouTube is often attributed to one or multiple Chrome extensions.

Outdated, corrupted, or incompatible extensions can significantly slow down YouTube’s loading speed.

For instance, in my case, the AdBlock extension was identified as the cause of the lag spikes.

Once I disabled this extension, YouTube resumed quick loading.

Apart from extensions, the simultaneous operation of numerous tabs and applications can also be a contributing factor to lag issues on YouTube.
