We are looking for a expert php or java programmer to optimise a php script or writing a new program.
The php script generates reports and graphs from textfiles. However this script is to slow.
The textfiles contain measurements; one measurement per line. The script needs to generate the reports faster (it takes around 90 seconds) for 100.000 lines.
The script also generates 3 graphs in PNG using jpgraph. Making the PNG's graphs takes around 65 seconds.
Script execution is commandline. However this can be changed to have a webinterface.
