How to use Perl to parse very big file without DB support?

来源: 德州老外 于 2006-08-21 16:40:41 [] [旧帖] [给我悄悄话] 阅读数 : (229 bytes)

I am parsing lot of huge log files now. Just wander how to speed things up. I have to read in 3 files at the same time. One file is huge, 300+MB. I have 1.5GB RAM now. The process looks damn slow.

Anyone has good idea?

• 速度还是提不上去，但是内存占用少多了。:D -德州老外- ♂ 给 德州老外 发送悄悄话 (0 bytes) () 08/21/2006 postreply 19:52:11
