I added 'compcache support' from pete's addons thru Rom Manager.
Do I need to do something else to use Compcache?
I believe to use Compcache you have to use Slayer Kernal. Download that on Rom Manager and then install compcache from Pete under BB Additional. Then once reboot go to terminal and type "compcache start" and then type "compcache stats" if you see a bunch of number, it means that it works. Hope this helps.
Maybe I should have mentioned that the link I said I found above
Enable CompCache in BBv05?
got me up and running with Compcache starting up at boot. I am using Slayher kernel, though I think some others may be compatible.
