Yep, perl is better for big text searches as far as the programmer is concerned, but it's not really all that fast. After all, regular expressions are literally integrated right into the language. No function calls. Much easier to work with.
I think it's primarily due to the precompiled nature of java BYTE-CODE. It's easier to translate byte values to other byte values for native machine instruction than it is for translating straight text such as perl to native machine instructions. Nope, no database backend. I used a plain text file. It has one verse per line. Example below. Genesis;01;001;001; In the beginning God created the heaven and the earth. I am thinking of switching to a database backend though. I'm using the regular expression package with JDK1.4.0. Then I have a split routine that I made myself for splitting up the book;booknum;chapter;verse;versetext into their separate parts. The new String.split () isn't fast enough because it's got the overhead of all possible regular expressions. In fact, I reduced a search from like 1300ms to less than 800ms by switching to my new split. The reason it's a big improvement is because it's in a loop. I could do extra programming to work around the fact that it has to be in a loop every time, but I figured it's not worth it. It's mostly JSP for the HTML part, then I have a bibleSearch method with a simple bean. Who knows, maybe it's not actually faster! Maybe יהוה has made it faster without my knowledge.

I always thought perl was better for big text searches... Did you give it a database backend? What API are you using for the search? Or is your performance improvement strictly due to the precompiled always-on nature of servlets (as opposed to interpreted perl)? -August --- Sébastien_Dui <[EMAIL PROTECTED]> wrote: > Let's hope that it will also work for applications without acts of > god... > > > > -----Message d'origine----- > De : Trenton D.
