　    一键部署OpenClaw        页面打开超过3秒，一半用户会关页。

二 | 速度优化不是玄学，就是压缩、缓存、延迟加载三板斧。    第一板斧，开Gzip压缩。HTML、CSS、JS这些文本文件压缩后体积能减小60%到80%。    # Nginx开启Gzip压缩（nginx.conf）    gzip on;    gzip_min_length 1k;    gzip_comp_level 6;    gzip_types text/plain text/css application/json    application/javascript text/xml    application/xml application/xml+rss    text/javascript image/svg+xml;    # 静态资源设置缓存（浏览器缓存）    location ~* \.(js|css|png|jpg|jpeg|gif|ico|svg|woff2)$ {    expires 30d;    add_header Cache-Control "public, no-transform";    }    第二板斧，图片延迟加载。

三 | 页面上的图片不用一次性全部加载，滑到哪里再加载哪里。这对长页面特别有效。    DRAPER, Utah -- A midair collision between a hang glider and paraglider in Utah killed the paraglider pilot, seriously injured his passenger and injured the pilot of the hang glider, police said Wednesday.The two aircraft collided and crashed around 5 p.m. Tuesday near Salt Lake County Flight Park, a popular spot for non-powered aircraft to launch from a mountain slope and catch updrafts in Draper, a suburb south of Salt Lake City.Both non-powered aircraft took off from the park and went down hard in the same area nearby, Draper Police Lt. Mike Elkins said.Paraglider pilot Joshua Ellison, 44, died before he could be taken to a hospital. A female passenger flying tandem, whose identity was not released, was in critical condition at a hospital, Elkins said.The hang glider pilot went to a hospital with unknown injuries, Elkins said.A hang glider is a triangular, kite-like aircraft flown by a pilot who is suspended horizontally underneath. A paraglider is an elongated parachute designed to glide with a pilot suspended in a seated position.Ellison was an experienced paraglider pilot. Conditions at the time were clear and mild. Few accidents have happened at the park in the past 15 years, Elkins said.“Generally, for the amount of traffic, they are very well versed,” Elkins said. "This is very rare. Our hearts go out to that community.”。                第三板斧，PHP OPcache。如果用的是PHP程序（WordPress、织梦等），开OPcache能缓存编译后的字节码，减少PHP重复编译的开销。    # PHP OPcache配置（php.ini）    opcache.enable=1    opcache.memory_consumption=128    opcache.interned_strings_buffer=8    opcache.max_accelerated_files=4000    opcache.revalidate_freq=60    opcache.fast_shutdown=1    另外，大图片用WebP格式代替JPG，体积能小30%到50%。服务器开HTTP/2，多路复用连接，加载多个文件更快。这两个也很重要。
