The reason you see more than 100 GB of virtual memory is related to a sandboxing technique. My understanding is reserving a large virtual address space is somehow useful for security.Added falkon, supposedly a lightweight browser. Not really.Given how many browsers are based on how few rendering engines, it may be hard to find any browser that really acts differently, memory wise. (Netsurf is one of the few that uses its own engine. See here.)Code:
VIRT RES SWAP USED %CPU %MEM TIME+ COMMAND 889.1G 1.0G 0.0 1.0G 0.0 12.2 15.19 chromium 38.6G 1.2G 0.0 1.2G 0.0 14.8 55.35 firefox 226.8G 525.6M 0.0 525.6M 0.0 6.3 8.36 epiphany 188.1G 546.0M 0.0 546.0M 0.0 6.6 10.26 falkon 645.2M 72.0M 0.0 72.0M 0.0 0.9 11.97 netsurf-gtk 102.7M 17.1M 0.0 17.1M 0.0 0.2 0.15 dillo
Most of those virtual addresses are not mapped. The column labelled USED is more useful.
