The file might fit without much problems in the filesystem cache, so i guess it would only be a problem in the first time.
I had a friend in university that used a refurbished hp workstation with a shitload of ram as a desktop computer, and he would find | xargs -L1 cat {} > /dev/null everything in his home directory on login to warm up the filesystem cache. The kernel would then drop stuff not actually needed/accessed nicely over time.
