Re: [OpenWrt-Devel] LUCI works extremely slow...
I am by no means an expert, but i recently did up/downgrades from 12.09 to trunk and back (after finding 12.09 would oom during boot) using the suggestions here: http://wiki.openwrt.org/doc/howto/generic.sysupgrade#free.up.ram In addition to that, i spent quite some time figureing out what all processes i could kill without killing the router. Good luck!

Re: [OpenWrt-Devel] LUCI works extremely slow...
Hi Jinzcheng. Indeed, you are correct that LUCI's speed of operation would not be directly related to memory requirements for a v3.x kernel. Likewise, Manuel is correct that older versions of OpenWRT should run OK with 16MB RAM, e.g. Backfire v10.03.1 or so, and that pre-compiling LUCI's source files could yield some performance improvement. The OP didn't specify which version of OpenWRT he is using, and I assumed it was a newer one incorporating the v 3.x kernel. I responded, since I was suggesting the slow LUCI could also be due to the kernel leaving too little available RAM for lua and other application-layer elements.
