>I ask because I have just been trying to use Twitter via Chromium on a
Raspberry Pi 2 running Raspbian and Twitter was unusable. Half the tweet could
be typed before any characters became visible and clicks within the text would
take a while to move the 
cursor.

 You would be moving from a 900MHz quad core (presuming you mean RPi 2
Model B) to a 1.5GHz quad core (Rpi 3B is 1.2GHz and RPi 3B+ is 1.4GHz).
Since Raspbian is still built as a unified (common to all models) 32-bit
OS, the 64-bit cores of the RPi 4 (and RPi 3) may be underutilized --
especially if one is running computationally heavy jobs. The 2B is running
60% of the speed of the 4B.

 The main speed up may be that the 4 appears to have true Ethernet
on-board, and not a USBEthernet adapter. That means your keyboard/mouse
going through USB won't be competing with your network (presuming wired
Ethernet -- I'm not sure what impact using a WiFi connection would have).

 The other significant change may be in the graphics driver. From what
I've read, the 4 is capable of directly poking the graphics processor,
while older models have to go through some proprietary library.

 Using a USB3 external drive for user data and temp files (eg: mounting
/home and /var onto an external drive) might help speed some things up.
