Be aware that Phex can easily use up to 40MB RAM. Then there is not much left for the system. This can be a critical system configuration.

This doesn't sound unusual. Other clients are sending search requests to you. They are quite small. Your Phex is returning the search results found in your shared files. Since the search engine is now working right in Phex 0.5 it really finds more files and returns this data wich is much more outgoing then incomming. All you can do is reduce the network speed but this is also only making sense if you like to use your connection for other things then Phex.

True... this is still from Furi the original client where Phex is based on... sorry we can't do everything at once.

I also like this jumping blue line. Maybe in one of the next release it will be gone and the host catcher removed. I already have some code for it prepared...

We always have to make a tradeoff between performance, functionality and memory size. Currently memory is the most cheapest resource and most of the time we will go for functionality and performance on the cost of memory. But actually on the 0.5 release we were able to find many memory holes and fixed them. Phex is running at stable memory for days...

Thanks for your feedback. It's always welcome.
