Why does perl consume my entire CPU?
Posted on June 20, 2007
I use a perl script to convert an Excel file to CSV on an Ubuntu mail server. It's a reasonably high specification machine. But then again the Excel spreadsheet is quite large too. It takes about 5 minutes to convert. During that time, CPU use hits 100% but it only takes 16.5% of memory.
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
5559 root 25 0 87520 83m 1688 R 100 16.5 0:06.35 xls2csv
Annoying.
I wish I could use the catdoc alternative written in C, but it freaks out with Japanese character sets.
