File causing the problem

Hi,

Previously, Calc could not open this file at all. The bugged was tracked here and fixed.
 
https://bugs.documentfoundation.org/show_bug.cgi?id=68016
 
There is still a performance issue. Calc is still rather slow to open the file and initial switching between the sheets is also slow. Subsequent switching between the various sheets is fast and responsive.

I posted a video to illustrate the problem here:
https://www.youtube.com/watch?v=UQSOiOreLxw

I've attached the problematic file.

A 10MB excel file is huge and probably slow opening times are to be expected here.

In my test with LO vanilla 5.0.1002 it took a few minutes without having the file loaded while excel was already done loading after less than a minute. Having to force quit LO. File never opens. Looks as if LO crashed.

Attaching log.

Confirmed → NEW.

Steve, thank you for testing but you should know that the actual problem with hanging while attempting to open this file was fixed in 5.1.0-master.
 
Please see (closed) bug for details:
https://bugs.documentfoundation.org/show_bug.cgi?id=68016
 
I opened this new report as instructed by Tobias and Julien because performance of opening the file will need to be addressed at some point. When someone has the time to look into it.
 
If you can, compare it to the speed with which Excel 2007 or later manages to open the same file. It's way faster.

If you want to, you can try using the daily build in parallel. For OS X the instructions are here:
 
https://wiki.documentfoundation.org/Installing_in_parallel/OS_X
 
I use Ubuntu myself.

Forgot to add link to daily builds:

My bad, sorry. Retested with nightly from today. Opening times on OS X 10.10.5:

LO ~1,5min
Excel ~1,5min

I don't see much difference in the opening time. 9,2MB for an Excel file is pretty big, not sure if this is to be expected.

Hi Steve,

That is odd. Excel 2007 is *really fast* to open this file:

Were you using MS Office for OS X? Which version?

Hi,

This bug is still present in LO. The version I'm currently using:

Version: 5.2.1.2
Build ID: 1:5.2.1~rc2-0ubuntu1~trusty0
CPU Threads: 4; OS Version: Linux 4.4; UI Render: default; 
Locale: ro-RO (en_US.UTF-8); Calc: CL

There is one improvement to what I initially reported. Switching between sheets after the document loaded is happens fast now. Previously it would take a bit until the switching actually happened.

The file still loads very slow compared to Excel 2007 running in CrossOver (wine)
