TM performance

You can tune the performance of a translation memory (TM) in terms of fuzzy index and statistics.

Trados Team can perform the re-indexing and recomputation tasks in the background, so that you can do something else in the meantime.

Re-index TM

TM are re-indexed from scratch. The re-indexing process goes through each TU, finds the tokens (words), and then computes the fuzzy indexes. Do this, for example, if you enable recognition of dates or variables after you change token recognition.

Statistics

Words that occur very frequently in translation units (TUs) are not useful for fuzzy indexes. Typically, these are words like a, the, to. Re-compute statistics removes the 1,000 most frequent words from the fuzzy indexes. This can make a difference in performance for large TMs. If the TM has less than 50,000 TUs, it will not make a noticeable difference.

upLIFT alignment status

upLIFT alignment is the fragment alignment (also known as FGA) that automatically occurs for TMs which have 5,000 TUs or more.
