I'm working on an editor that I've optimized for such cases. In a test it made random edits to a 4GB file in < 50 microseconds. But, it cost a load of sweat and blood to get that rope data structure right. And it loads files only at about 100MB/s (should optimize for bulk inserts). https://github.com/jstimpfle/astedit https://github.com/jstimpfle/astedit
- userbinator 7y agoAre we at > 10GB/s memory bandwidth now? It's been around a decade since that line was crossed. The peak bandwidth of DDR3-1333 is just a bit over 10GB/s.
- cerberusss 7y agoInteresting project. You don't say so specifically, but it looks like it should compile on both Windows and Linux?
- jstimpfle 7y agoYes, I make it to compile on both platforms from time to time. The current commit should compile using MSVC, gcc, and clang I believe. I'm happy to fix any issues if you find them :-)
