Your DROID BIONIC contains a hidden feature where network buffering parameters within its Linux kernel are modified and managed according to the type of network connection you are using. For unknown reasons, Motorola and Verizon have the buffer sizes for their 4G LTE link set comfortably high while all other network links (including WiFi) are set very low.
This app provides a tweak to /proc/sys/net/ipv4/tcp_[r|w]mem and /proc/sys/net/core/[r|w]mem_[default|max] to increase the buffer sizes for WiFi and 3G to those used by the 4G LTE link.
Takes effect immediately, and modifies the properties for 'wifi' and 'default' profiles so they match those of the 'lte' profile. This ensures the new settings take effect seamlessly as you switch between wifi and 3G or 4G LTE.
Provides a "Default TCP Buffers" button to roll back to the Bionic's default settings.
This app does not load these settings upon reboot automatically; you will have to load the app manually after a reboot to force the settings into effect. I will look into automating this later.
I have not run any speed measurements to prove out whether this improves network performance, but with my own usage it does seem that webpages load quicker and don't "hang up" as often during loading. It's a subtle difference. YMMV.
