Description sisi1 2004-04-18 21:15:10 UTC
V případě, že je vloženo do jedné nebo více buněk Calcu velké množství
zalamovaného textu (4-15 kB)dochází k viditelnému zpomalení systému, kvůli
vytížení CPU. Při pohybu kurzorovými šipkami cca. 70-90%. Při pohybu myší nad
buňkou s textem je vytížení 90-100% až do zastavení pohybu. Stejné operace v
Excelu zatěžují CPU cca. 4-12%.
If in Calc there is entered into one or more cells a lot of text (with LF)
aprox. 4-15kB then reaction of system is visibly decreased. It is caused by
overloading CPU. When cursor keys are used for movement through these cells, the
CPU is loaded   from 70 to 90%. When mouse pointer is moved across cell with
that text the CPU is loaded 90-100%. The same actions in Excel load CPU from 4
to 12%.

Dan, please investigate (if you have a minute).

I can confirm it, the same on linux, in versions 1.1.0 and 1.1.1.

On my system is the cpu load not too high, but there are unusual delays in
displaying the contents of spreadsheet in in page scrolling.

There are also other problem related to this, the text in editing line is
improper formated and displayed. See attachment.

Probably we shouldn't try to format text, which is not shown.
