Hey all,
I just put preload into portage. I found this one by researching readahead stuff. Preload is an adaptive readahead daemon. This is a cool little app that I have been running all day now. The short story is that it scans /proc every 20 seconds and will maintain its own “database” of files to keep loaded in memory.

The long story is: The author’s whitepaper on preload. And more details can be found [here][2].

Anyway, I could use testers on this package. I have observed noticable speedups on the first launch of apps like firefox, thunderbird, & vim. This does work and it is very smart. It cannot use “all your ram” and it has tons of configuration options. Please provide feedback, and file bugs as appropriate. Thanks.
