As much as I like and want to use Transmission, the 0.9x releases have been terrible in my experience.
- Crashing bad on Quit
- Ultra-slow download speeds
- Screwed port-mapping
- Files bloating up then not working
- Files part downloading then restarting from 0% if you reload the app (not fun when you waste Gbs of bandwidth)
- Hash checks seem totally random and inaccurate
I came back when 0.72 was released and trialled it for a good while until 0.82. They did not suffer as badly but downloads are not as quick as other clients. Once 0.9x hit, problems again. Thus, sadly, I'm stuck with Azureus again. Somehow I always go back to it but it seems quite OK thesedays. Not keen on the Vuse thing at all, though but speeds are lightning-quick and it finds many more peers than Transmission ever did.
Reading the Transmission forums form the 0.96 tests, I can't be certain the bloating files and loss of part downloads is 100% fixed. Hopefully Transmission can return to glory soon.
