Re: PHP to C translator

As posted earlier.... Well, the scripts do not iteract with a database. They read a some text files from disk, do some calculations and output some more text files to disk. The calculation part is super-fast. The output part is super-fast also. BUT, the reading part from the text files is painfully slow.... For a text file of 350MB, the script run from PHP3 takes about 1.5h. For the same text file, the script run from PHP4 takes about 30m. (wow, that *is* an improvement, 300%). All files are local to the machine. Judging from the HDD led activity (yes, not a very reliable indicator) I think it can be done faster. I haven't tried the Zend optimizer, yet. I'm running on SuSE 6.4, AMD-K7/500, HDD-UDMA66, 256MB RAM. Any more ideas? Thank you fro your time, -Stathis.
