Hi, Talking briefly about the size of games nowadays and SSD, i checked some stuff and saw Firefox writing 4.5 Mo/s (= MB/s). I wanted to see what that was, and saw it's mainly firefox cache. From there i searched and found a few sites suggesting and showing the settings to change to switch from disk cache to RAM cache. I did so since i've enough free RAM from a little while now. Changed settings (in '''about:config'''): * '''browser.cache.disk.enable''' from '''true''' to '''false''' * '''browser.cache.disk_cache_ssl''' from '''true''' to '''false''' '''browser.cache.memory.enable''' was already on '''true''' and '''browser.cache.memory.capacity''' on '''-1''' (not sure it's the best setting, only displaying 32768 KiB in about:cache... Any insight appreciated). The concern: Cf. title, about:cache is still displaying the cache is also on disk, while i don't see writings being done related to the cache on the SSD. Is it just a display error in this configuration, or is there something else? If it's an error, i guess i should report it if it's not already done on the appropriate platform after. ''Also, i hope the 4.5 Mo/s was just a peak, because if it's constantly like that if you've Twitch opened for instance, that's a major issue. On a SSD like the Samsung 850 EVO 250GB with its small TBW of 75, that's slightly less than 193 full days.''
