Telegram desktop client is written in C, takes 20MB or ram and can download 1,000 messages in 3 seconds.

Teams takes 500MB of ram and pegs a quad-core cpu to 70% to updates some smileys

Even mobile Telegram is so small and efficient despite being feature-packed. Just compare 67Mb of the Telegram installed Android app with 156Mb of Discord, 623Mb of WeChat, etc.

thou for ppl that grew up with operating systems on floppy disks, 67MB is quite a load for a chat software ;)
