Adding a couple of dnsmasq optimizations based on forum thread:

http://www.linksysinfo.org/index.php?threads/dnsmasq-cache-optimization-and-howto.23076/

It appears safe to increase the dnsmasq cache to 2048 on ARM, as people have been running with 10,000 on old WRT54GL routers.

In addition, enabling asynchronous logging for dnsmasq, which can potentially remove/reduce deadlocks with syslog, but also, generally provide better performance under load.
