How do I find and increase the number of peers Tix connects to.
Take a look in the Settings > Network > Connections.
It does not mean you will connect to all of the peers, they will have their own limits.
Off topic question, but why does Tixati find it necessary to use 1 GB of RAM??? No other torrent client has this problem (As far as I am aware).
First of all: the channels feature. The shares take up a lot of RAM! Practically you don't need to join more than 2-4 channels because most users' shares are duplicated in multiple channels. To permanently clear the memory: Channels > Remove channel (you can gather it for the list, but don't join it again), then restart Tixati.
I heard people talking in one of the channels about this. They seemed suggested that shares may be being kept in RAM, why? I'm not the dev (Obviously) but wouldn't it be better to cache that stuff to disk since it rarely changes and the user doesn't request that information very often?
I think the way channels work they must keep the information in RAM. At least the online channels, theoretically offline channels shouldn't require their data to be loaded (except for search).
Last but not least Tixati needs more memory the more shares (files) are loaded. Someone told me this is being worked at to be offloaded to disk.
