Oddly, It takes now only 23 sec.

This is an ASUS L8400C Notebook with PIII 850MHz with 384MB RAM. From 
the Spy output:

75205640 bytecodes/sec; 2277950 sends/sec

    Seams okay.

    I have no problem on small tasks but on very large tasks. Try to do 
it on 500000 entries and report your finding (if you'll have a valid 
image after that...
)
