Description alfeno 2007-09-12 14:10:52 UTC
Ooo writer has poor performance when it try to convert a large volume of data to
table. All data has separate of space charset.

I select all data "Ctrl + a"
Select a option "Table" in menu bar > Convert > Text to Table.

Obs: In "convert text to table" windows i inform to OOo writer the column is
separate of space charset.

In Ooo writer processing for 15 minutes in my computer and it can not to convert
(Ooo_bug.png). In Microsoft Word successful convert in only 3 or 4 minute
(MS_Word.png).

My computer is a Intel Pentium IV 2.80 Mhz with 512 RAM running windows XP SP2.

 - OOo 2.2.1 - 4 min + crash when start scrolling
 - MS Word 2007 - <2 min

2. Athlon64 3700, 2Gb RAM, WinXP SP2:
 - OOo 2.2.1 - <3 min
 - MS Word 2007 - <2 min

Canis;

You can test it in a more modest computer ?

I tested in AMD Athon XP 1700+, and Ooo writer has poor performance

Can confirm with OOo 2.3 RC(1-2?)

AMD Athlon 1 GHz, 1.2 GB RAM
Win2k SP4
Real-Life Workload

After > 12 min NO reaction from OOo Writer. Will let it an additional 10
minutes, to see IF anything happens. But chances look grim for a success.

Well, after well over 30 minutes, NO reaction from OOo 2.3 RC1(or 2?). I
therefore killed the process.
Comment 9 alfeno 2007-09-12 19:13:11 UTC
I tested with OOo writer 2.3 Release Candidate 3 (build OOG680_m5). I've the
same poor performance.

MRU->AMA: converting large amounts of data like in the attached txt takes about
3 or 4 times longer than in another product. When I tried with OO 2.3, it took
about 15 min to finish.
Please have a look, if this could be optimized anyway. Thanks.
