My main laptop is a Thinkpad T61, my office desktop is a 2006 mac-mini, so yes, I fully agree. >> The emacs-w3m fetches the page asynchronously, but the rendering process >> will freeze Emacs for a long time. > Yes, this is an actual problem.

One of the reasons why we can still use 10+ year old computers is because even the fanciest newest CPUs aren't *that* much faster (on single-threaded code, as is the case here) thanks to the end of Dennard scaling, so if it's "less than a second" on Óscar's computer there's a good chance that it should be much less than "a long time" on the OP's machine. IOW there's probably some other difference than the hardware at play here. Stefan
