Can I suggest that if you&#x27;ve got problems including &quot;stalls for tens of seconds on disk reads&quot; you are almost certainly better off directing available resources towards fixing your hosting problems, rather than going down the cache rabbit hole  on a hosting platform that&#x27;s not really suitable for production use?<p>(With caveats for zero resource projects of course, but even for those I strongly suspect for many people paying $5 or $10 per month for &quot;less crap hosting&quot; is probably a better solution that prematurely optimising by adding caching and all it&#x27;s inherent complexity to a fundamentally broken platform)
