Hi

I'm experiencing severe performance issues when using the transmission bit torrent client. Bassically the UI of my N900 turns non responsive, lagging seconds to process screen clicks.

Is someone seeing this? The phone performs fine when transmission is not started.

I have checked with a top and i just see light cpu load from 10 to 25%


Does anyone have a clue?

Regards and thank in advance.

Carlos

Yes it sucks a lot of juice so I don't use the phone when getting my torrents. it works great though with Pirate Bay torrents etc.

You might want to limit the amount of connections Transmission is making in settings. I think I read on this forum a few months back that helps with performance.

yes it slows everything else down a lot. The application is yet to be properly optimized for this platform. I have confidence that things will change soon.

I can confirm Laughing man comment, reducing the maximum number of threads helps a lot. I guess that there are too many context switches or something like that...

Is it even being actively developed?

a torrent site i know insists on version 1.8 or higher. the n900 version is 1.75 or so.

I am not a real hacker but I notice on the transmission site that there is a more recent qt arm compiled package. So what would I do to get this to work?

Re performance, it's not the CPU, it's the disk I/O that hits it. I don't use transmission, but I'd try save to microsd instead of emmc, it might help a bit since then transmission wont be competing with swap for the limited IOPS available.

And it's responsible to run this type of programs that do so many writes in the emmc??
Can't the flash memory wear out too quickly with this?

I have a small server at home (SheevaPlug), downloading torrents all day, and after a few weeks I had some bad blocks in my SD card, anyway the problems seems not to be increasing...

Anyway, I would run transmission in mircroSD so if it gets broken you would be able to change it

Actually, it is provider scalability restrictions. Look - your phone works in 3G environment, but it's IP address is different from public. So, you work behind provider NAT... and his router has a performance restrictions on number of opened TCP/IP connections.

The same problem does exist, for exam, with some D-Link routers on home WiFi - bittorrent also should scale back the number of connections to work properly with it. But after replacement of D-Link firmware with Linux-based DDR-WRT the problem disappears... because linux has much higher limits on it.
