A web browser is a huge and complex app. The argument it struggled with memory issues is moot if you can't show a comparably featured app written in Java to compare memory use.
Anyways, I've got plenty of anecdotal evidence where Java apps take order of magnitude more memory than their close counterparts written in languages that use manual memory management. Not browsers, but things like benchmarking tools, webservers or even duplicate file finders (shameless plug: https://github.com/pkolaczk/fclones#benchmarks https://github.com/pkolaczk/fclones#benchmarks - there is one Java app there, see its memory use :D)
- foldr 5y agoWe’re talking at cross purposes here. I did say that I wasn’t expressing a view as to whether the overheads of manual memory management are typically larger than the overheads of GC. I don't know if they are or not. The point I was making was just that you do need to compare empirically the typical overheads of each to make a meaningful comparison. The 6% figure in isolation doesn’t tell us very much. As you point out, it is difficult to make these comparisons on the basis of anything other than anecdotal evidence, since it is rare for applications of significant size or complexity to be implemented in multiple languages.
