Version: unspecified (using KDE 4.4.5) OS: Linux Dolphin currently does not support multithreading and at times high CPU is required for things like generating thumbnails, searching in large no. of files etc... Reproducible: Didn't try
Thanks for the suggestion. The generating of thumbnails, the getting of meta-data, searching in files etc. is done asynchronously in custom threads/processes. If there is a performance issue in Dolphin, it of course has to be fixed, but threading is not always a solution. I'm closing this bug as invalid, as it is to vague: If you have a specific usecase where Dolphin hangs, I'd kindly ask to open a new bug-report so that we can decide then how to fix this specific issue by e.g. threading or somehow else.
Dolphin is very slow when opening ~2000 pictures with thumbnails enabled... the cut paste of a few files (~500 KB) takes ~30 seconds in the same partition. I'm running AMD Athlon(tm) 64 X2 Dual-Core Processor TK-55, the HDD on average gives 40 - 50 MB/s. Memory is never complete occupied.
