T-LAB performances depend basically on two factors: the corpus dimension and the kind of CPU available.

At present, T-LAB options have the following restrictions:

• corpus dimension: max 30Mb, equal to about 18,000 pages in ASCII format;
• primary documents: max 30,000;
• categorical variables: max 50, each allowing max 150 subsets (categories) which can be compared;
• modelling of emerging themes: max 15,000 documents by 1,500 words;
• thematic analysis of elementary contexts: max 150,000 rows (context units) by 1,500 columns (lexical units);
• thematic document classification: max 30,000 rows (context units) by 1,500 columns (lexical units);
• specificity analysis (lexical units x categories): max 10,000 rows by 150 columns;
• correspondence analysis (lexical units x categories): max 10,000 rows by 150 columns;
• correspondence analysis (context units x lexical units): max 10,000 rows by 1,500 columns;
• multiple correspondence analysis (elementary contexts x categories): max 150,000 rows by 250 columns;
• cluster analysis that uses the results of a previous correspondence analysis: max 10,000 rows (lexical units or elementary contexts);
• word associations, comparison between word pairs and co-word analysis: max 1,500 lexical units;
• sequence analysis: max 1,500 lexical units (or categories) by 3,000,000 occurrences.
