Read a 233MB CSV file into Calc without problems. Attempted to write it out as CSV with slightly different options ("quote everything"), and it's half done after an hour. About 2/3 done after an hour and a half. Progress continues. Calc is in the "greyed out" state, not processing mouse clicks. Since this is on Linux, it doesn't affect other processes much, and I'm letting this run to see if it finishes. It's not hung; the progress bar advances slowly. CPU utilization 100% of 1 CPU. Very little disk I/O. Memory not full. Not thrashing. Very little I/O, maybe one disk write every 10 seconds. This looks like there's something in writing out a CSV file that's worse than O(1), so it chokes on large files. Somebody with a debug build should profile this while writing out a large CSV file and see where it's spending all the CPU time. Ubuntu 16.04LTS x64 8GB. Calc version: libreoffice-calc 1:5.1.6-rc2.0ubuntu1-xenial2</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
