From: fschaper at intux dot org Operating system: WindowsXP PHP version: 5.1.2 PHP Bug Type: Performance problem Bug description: perfomance loss since php version 5.05 Description: ------------ Since php version 5.05 we noticed an rather large performance hit in general while working with rather large array's. We have prepared an short sample which illustrates the problem. in php5 the script takes about 0.5 seconds to perform. The latest snapshot release from today and the current release version of php take about 4.5 seconds for the same task.
