[Monotone-devel] monotone serve thrashing

[Glen Ditchfield]

I have monotone 0.19, compiled on SuSE 9.2 from the source rpm.  I used  
monotone serve to serve a 250MB database, and synced with a brand new empty 
database.

The server has only 196 MB of real memory, so I wasn't expecting instantaneous 
response, and I walked away.  When I came back 9 hours later, the top command 
said that the monotone serve process had consumed 43 minutes of CPU, but had 
caused 1.9 million page faults.  Virtual image size was 251 MB, and resident 
set size was 152 MB.  The syncing process on the other computer had received 
6.7 MB in.

I gave up and copied the database to the other server.  Since then I have 
synced the two a few times.  The amount of data transfered was never large, 
and the commands completed in seconds -- typing in my pass phrase is the 
longest part of the process.
