Loading the entire pagelinks table from ruwiki took roughly 60 seconds.
(I didn't measure that step separately, but the entire run was 1:25,
most of which was loading the data.)

I'd have to see a more detailed description of how you tested it to
answer that, but 1MB in 2.5 minutes seems far too slow.
For raw disk writes to /home:
% time mkfile 100m test
mkfile 100m test 0.00s user 0.28s system 12% cpu 2.155 total
i.e. 100MB written in 2.1 seconds, or 47MB/sec.
