We try to keep the Tahoe memory footprint low by continuously monitoring the
|
||||||
|
memory consumed by common operations like upload and download.
|
||||||
|
|
||||||
|
For each currently active upload or download, we never handle more than a
|
||||||
|
single segment of data at a time. This serves to keep the data-driven
|
||||||
|
footprint down to something like 4MB or 5MB per active upload/download.
|
||||||
|
|
||||||
|
Some other notes on memory footprint:
|
||||||
|
|
||||||
|
* importing sqlite (for the share-lease database) raised the static
|
||||||
|
footprint by 6MB, going from 24.3MB to 31.5MB (as evidenced by the munin
|
||||||
|
graph from 8/29/07 to 9/2/07).
