GEDCOM Import Speed
I’ve made an overview of the GEDCOM Import speed numbers I reported in reviews.
I already added numbers for some major applications and genealogy viewer. This
overview adds numbers for some popular Palm applications.
2008-05-25 GedStar Basic 5.2
| file | 1 MB GEDCOM | 100k INDI GEDCOM |
|---|
| time | 4s | 29m35s |
| time in seconds | 4 |
1.775 |
| INDI per second | 1.215,50 |
56,38 |
| bytes per second | 263.973,75 |
21.858,81 |
The time for the 1 MB GEDCOM is between 3 and 4 seconds. It is hard to say how
fast exactly, but certainly fast enough. Alas, the performance drops
dramatically for larger files.
GedStar shows a detailed progress dialog box.
2008-05-25 GedStar Pro 3.2
| file | 1 MB GEDCOM | 100k INDI GEDCOM |
|---|
| time | 4s | 16m53s |
| time in seconds | 4 |
1.013 |
| INDI per second | 1.215,50 |
98,78 |
| bytes per second | 263.973,75 |
38.301,47 |
The import time is the time needed to convert the database to GedStar Pro
format. The time to HotSync with the Palm handheld is not included.
GedStar Pro display a detailed progress dialog that shows exactly what GedStar
Pro is processing and what the progress is so far. With the larger database, the
import second phase, cross-referencing the individuals, takes most of the time.
If GHCS Software took a good look at that phase, they could probably reduce the
import to less than half what it is now.
While importing the 100k INDI GEDCOM, some 38 MB, the Task Manager showed the
memory usage climbing to and remaining constant at 183 MB. GedStar Pro reports
that the resulting database is 19,3 MB, but it is actually just 18,5 MB.
2008-05-25 GedWise 6.2
| file | 1 MB GEDCOM | 100k INDI GEDCOM |
|---|
| time | 7s | 10m03s |
| time in seconds | 7 |
603 |
| INDI per second | 694,57 |
165,95 |
| bytes per second | 150.842,14 |
64.343,94 |
GedWise not only shows detailed progress statistic, it also shows the time it
takes to perform the database conversion. In my experience, the time displayed
is indeed the total time. but probably rounded down. The import time for the 1
MB GEDCOM is probably close to 6⅔ seconds, which I report
as 7 seconds, and GedWise itself reports as 6 seconds.
