Configure the viewport

Your page does not have a viewport specified. This causes mobile devices to render your page as it would appear on a desktop browser, scaling it down to fit on a mobile screen. Configure a viewport to allow your page to render properly on all devices.
Size tap targets appropriately

Some of the links/buttons on your webpage may be too small for a user to easily tap on a touchscreen. Consider making these tap targets larger to provide a better user experience.
The following tap targets are close to other nearby tap targets and may need additional spacing around them.
The tap target <a href="http://www2.2ch.net/2ch.html">掲示板</a> and 1 others are close to other tap targets.
The tap target <input type="text" name="q"> is close to 1 other tap targets.

Optimize the following images to reduce their size by 107.2KiB (70% reduction).

Compressing http://spcdnpc.i-mobile.co.jp/ad_creative.ashx?advid=2853926 could save 40.8KiB (68% reduction).

Optimize CSS Delivery of the following:
http://2ch.net/2ch_top.css
Prioritize visible content

Your page requires additional network round trips to render the above-the-fold content. For best performance, reduce the amount of HTML needed to render above-the-fold content.
The entire HTML response was not sufficient to render the above-the-fold content. This usually indicates that additional resources, loaded after HTML parsing, were required to render above-the-fold content. Prioritize visible content that is needed for rendering above-the-fold by including it directly in the HTML response.
Only about 43% of the final above-the-fold content could be rendered with the full HTML response.
Leverage browser caching

Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.
Leverage browser caching for the following cacheable resources:
http://img.bbchat.tv/images/bannar/46860-3.gif (expiration not specified)
http://spnet2-1.i-mobile.co.jp/css/style.css (expiration not specified)

Enable compression

Compressing resources with gzip or deflate can reduce the number of bytes sent over the network.
Enable compression for the following resources to reduce their transfer size by 31KiB (67% reduction).
Compressing https://spdeliver.i-mobile.co.jp/script/ads.js?20101001 could save 27.4KiB (69% reduction).
Compressing https://cdn-fluct.sh.adingo.jp/f.js?G=1000070518 could save 972B (52% reduction).
