I've got this result on my Ubuntu 64bit box
benva@benva-laptop:~$ ps aux | grep tpsieve
benva 4583 199 18.9 782044 757800 pts/0 Sl+ 13:24 575:08 ./tpsieve -p9100e12 -P9150e12 -itpsieve_7300TE1.txt -ftpsfactors_9100T-9150T.txt -t2
In my case cpu usage is near 200% (199%) so it's ok.

The link in Lennarts post goes to a page called "Parkerad hos Loopia." ???
There's a typo, the correct link should be

The issue was on priority set to idle in tpconfig. qmax already set to 10e6.

I think something's wrong with the linux builds, 64 bits at least...
I didn't test linux version of nwepgen yet.
