I’d been running on a 16 GB chip and the fat Macintosh software filled most of it, leaving just about 2 GB free for swap. Yet there’s one place where it’s been a Royal PITA. Often by adding large disk based swap areas on systems with smaller memory or adding real swap disk to systems running from an SD card. Generally I’ve been able to avoid the issue. IMO, that’s just sloppy lazy programming. Programs, like browsers, that used to run in 64 MB machines Just Fine now get cranky with less than 1000 MB ( one GB ).
Detailed information on memory use is also available in the about:cache and about:memory pages.The “garbage collection” in all sorts of programs has gotten much worse over the years, in direct proportion to the increase in memory sizes in computers. In some cases it may be useful for diagnosing memory problems, allowing the user to distinguish between cache use and other memory use, although the cache can also be cleared from the Tools menu, without this extension. This gives the advantage of small cache sizes without having to always suffer the performance hit. The RAMBack extension allows the user to manually free memory, such as caches, that is usually used to increase performance. Therefore, for most purposes the default value is recommended. If im_on_minimize is left set at the default value (false), the memory will be swapped to disk only if it is needed by another application. The im_on_minimize setting (Windows only) does not reduce the amount of memory used, it just swaps memory from RAM to disk. Each preference includes an estimate of the amount of memory that can be freed on an average (512MB RAM) system by choosing the most memory-friendly setting.ī and Read each article for the preference's effects. Settings that reduce memory usageĬhanging the about:config preferences below may have an effect on memory consumption but may also affect performance or reduce functionality.
