Hello!
Having to write millions of homogenous point features to a file geodatabase (default Esri File Geodatabase Writer 3D, Vector), I noticed that the duration for a completed writing transaction/commit increases as the writing to the FGDB progresses. While the first transaction takes 0.4 seconds for 1000 features, the duration increases up to 1.5 seconds per 1000 features where it seems to level until the end of the writing process (there are no other process running):
0.0|INFORM|Transaction #1 was successfully committed
0.4|INFORM|MULTI_WRITER: multi_writer_id `1': Writing feature 1000
0.0|INFORM|Transaction #2 was successfully committed
0.5|INFORM|MULTI_WRITER: multi_writer_id `1': Writing feature 2000
...
0.0|INFORM|Transaction #328 was successfully committed
1.0|INFORM|MULTI_WRITER: multi_writer_id `1': Writing feature 328000
...
0.0|INFORM|Transaction #503 was successfully committed
1.4|INFORM|MULTI_WRITER: multi_writer_id `1': Writing feature 503000
...
0.0|INFORM|Transaction #2289 was successfully committed
1.5|INFORM|MULTI_WRITER: multi_writer_id `1': Writing feature 2289000
...I know about the possibility to increase transaction size (https://docs.safe.com/fme/html/FME_Desktop_Documentation/FME_ReadersWriters/geodatabase/Improving_Speed_Writer.htm). However, I was wondering what might cause this kind of regression? I'm thankful for your hints...
