Comment:
The new maxima certainly comes with a bigger library; Its inevitable that
it is somewhat slower in exchange for being better at integration. I don't
know why startup is so slow on kcrisman's antique computer, but stracing
the maxima startup shows that it thrashes around quite a lot in the
`$SAGE_LOCAL/share/maxima/5.22.1/` directory tree.
For the record, Fedora 14 on a Thinkpad T410s Core i5:
{{{
sage: time integrate(x^3,x)
CPU times: user 0.03 s, sys: 0.01 s, total: 0.04 s
Wall time: 1.15 s
1/4*x^4
sage: time integrate(x^3,x)
CPU times: user 0.01 s, sys: 0.00 s, total: 0.01 s
Wall time: 0.05 s
1/4*x^4
sage: time integrate(x^3,x)
CPU times: user 0.01 s, sys: 0.00 s, total: 0.01 s
Wall time: 0.05 s
1/4*x^4
}}}
I say we should press ahead and update maxima so that Sage compiles on
Fedora 14. If the new maxima starts up slowly on your hardware then file a
ticket and see if you can profile/fix it.
