主题：Google开发网页的新工具Page Speed -- meokey

结果相当不错，唯一的优化建议是使用压缩

Enable compression

Compressing the following resources with gzip could reduce their transfer size by 84.1KiB (71% reduction).

Compressing http://www.ccthere.com/boards/ could save 44.3KiB (78% reduction).

Compressing http://www.ccthere.com/incs/rs.php?T=2&V=1 could save 26.9KiB (67% reduction).

Compressing http://pagead2.googlesyndication.com/pagead/show_ads.js could save 7.5KiB (59% reduction).

Compressing http://www.ccthere.com/incs/rs.php?T=0&V=1 could save 3.6KiB (67% reduction).

Compressing http://www.ccthere.com/intr/indexfun.php?DZ=3&T=3&RID=1&SID=0&SA=0&PIDRT=0&Rnd=1301497334999 could save 1.8KiB (59% reduction).
