That is the _first_ complexity - and on top, as you mentioned, is the _second_ complexity of websites taking advantage of all that power: primarily JS, its many frameworks, external resources and dependencies, lots of local computation and storage. It's quite funny that all the disadvantages associated with "Flash" now have become even more significant with JS. Many years ago, I tried opening 70+ tabs in Opera with "Flash", each one playing some video. That was on a dual-core machine with 2 GB RAM. With the 75th tab open, swapping started, but Opera still was responsive (albeit sluggish), so I could close the tabs, and system came back to normal. Funny thing: It seemed to be more I/O load than CPU load, and looked like this (copied from a terminal - yes, this was still possible): 1 [|||| 7.9%] Tasks: 73, 0 thr; 1 running 2 [| 2.6%] Load average: 0.38 0.70 0.42 Mem[|||||||||||||||||||1601/1990MB] Uptime: 00:52:33 Swp[||||| 275/2047MB] Now try _that_ today - with today's resource-intensive websites, with today's resource-intensive web browsers. Use a recent PC, put 64 GB RAM in them. Probably you won't even reach 50 tabs open... :-) > also ~80+ Firefox introduced some nasty ideas such as "profile downgrade > protection" so i can only imagine what kind of team took over the project > :-) Combine this with "use our online services and store your stuff in our cloud"-mentality... "our customers"... yes, definitely what I want from a "simple" program that displays web pages... ;-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
