## Memory Footprint
|
||||
|
||||
[The [MemoryFootprint](MemoryFootprint) page](MemoryFootprint) has more specific information.
|
||||
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 2007-08-29 to 2007-09-02).
|
||||
|
||||
* importing nevow and twisted.web (for the web interface) raises the static
|
||||
footprint by about 3MB (from 12.8MB to 15.7MB).
