My Webhost is saying Redis Useful resource Intensive — is that true?

I’m paying about 100$ a month for a VPS: 300GB SSD, 15GB Bandwidth, 24GB RAM.I requested data on object caching (web site is utilizing WordPress’ BuddyPress) as I used to be debating on whether or not so as to add Redis. The positioning is not even dwell but.The hosting firm is saying they’ll add Redis or Memcached however the service can be useful resource intensive, and that I’d must improve the VPS sources to stop overload.Does this sound correct? I used to be beneath the impression Redis was supposed to cut back impression on the server not enhance it? Additionally, for 100$ a month, I figured I would not must pay much more to assist object caching. Is there one thing I am lacking?
