Robin, It is certainly true that accessing all the data in a project is time-consuming, however, I don't think that excuses the relatively poor performance of the TMG export. As a comparison, I made a full site (everyone in the project) using Second Site (SS), and that took 3 minutes. To make a full site, SS must read most of the data in the TMG database, and a lot of it more than once. For example, if a Census event is shared by 5 people, Second Site reads that event 5 times. Each time, it evaluates which of the people can be shown, evaluates the sentence template for the subject, processes the citations, and inspects the exhibits. For my project, the full site includes 464MB of HTML and other files spread across 3,302 files. That is significantly more IO work than writing a single GEDCOM file. For my TMG project, the GEDCOM file is about 15MB, so SS is writing 35x more data. Some of the 3 minutes is used to copy the exhibit files. The project has 1,050 exhibits totaling 397MB. To be fair, it's easier to copy files at (relatively) high-speed than it is to create content and write it at high-speed. Even if we remove the 397MB from what SS wrote, it's still wrote 4x more than TMG's GEDCOM export. Meanwhile, not writing the exhibits shrinks the SS elapsed time by about 45 seconds. SS is 17 years old, and so it faces some of the same challenges as TMG in that regard. SS does more work to create a site than TMG has to do to create a GEDCOM file, and yet it finishes in 15% of the time while operating on the same database. I am a TMG fan, and parts of it were extremely well-designed and implemented. However, it is safe to say that the performance of TMG's GEDCOM import and export were not deemed important enough to warrant performance tuning. That's one reason why comparing the speed of the SS Make Site function to TMG's GEDCOM export is not fair; the performance of the Make Site command is much more important to SS than the GEDCOM export is to TMG. Lastly, there are users of SS who wait a lot longer than 3 minutes for SS to make a site, and so there is always room for improvement. John
