Hm. That is probably too long. It could, of course, be because of 
swapping; however, local commands run smoothly. cerezal is currently
doing backup uploads, the storage node runs with a running set size of
48 % RAM.  The backup itself does not seem to consume much resources,
around 0 % CPU and 5 % RAM. However there could be some interference
with file system caches which on Linux use any RAM not claimed by
programs. What could also cause problems is NFS service which I
was using to upload things.

To have an idea what is causing poor response times, I'll
switch off upload and NFS and would like to ask you to measure
response times again and send them to me.

Is it possible that the upload slows thing down by
clogging the network connection too much?
