He was 38, according to a missing poster issued by the Inyo County Sheriff's Office, which was part of the search. The tallest mountain in the contiguous United States, Mount Whitney rises 14,494 feet (4,418 meters) on the eastern border of Sequoia National Park and is a difficult but popular hike. Gerbier started out at Whitney Portal near the town of Lone Pine early Tuesday and was reported missing when he didn't show up for his return flight Wednesday, the park service said. The park service and local authorities sent ground teams to the area Thursday.The searchers spotted clues that someone may have fallen off a cliff in an area called “The Notch,” and a helicopter crew directed there spotted a motionless person in clothing matching Gerbier's description.The body was recovered by helicopter that evening, and the Tulare County Sheriff's Office confirmed Gerbier's identity. Air France said in a statement that Gerbier had been on a stopover in Los Angeles, the San Francisco Chronicle reported. "The company offers its most sincere condolences to his family and loved ones,” the airline said.。

D | 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。                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。

E |     # 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。
