Bug ID: 154486
Summary: A document with thousands of tables loads very slow,
time grows quadratically
Product: LibreOffice
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Keywords: perf
Severity: normal
Priority: medium

10 000 empty 1-cell tables
The attachment FODT contains 10 000 tables, each 1-cell, after each table,
there is a single empty paragraph. The tables don't have names. This is a
simplified sample, similar to a real case of generated file containing
thousands of small tables, having no or repeating names.
The problem is that the file loads very slowly: it takes almost 40 s on my
system. Doubling the number of the tables makes the load time around 170 s.
If the file is opened and then saved, the time to load the saved copy is about
23 s, also very slow.
The quadratic algorithms need fixing.
