Comment(by jpflori):
On my [wiki:QuadCore Core 2 Quad] running Debian, here are the timings for
the new Maxima:
{{{
sage: time integrate(x^3,x)
CPU times: user 0.02 s, sys: 0.01 s, total: 0.03 s
Wall time: 1.49 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: 0.06 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: 0.06 s
1/4*x^4
}}}
and with the old Maxima:
{{{
sage: time integrate(x^3,x)
CPU times: user 0.01 s, sys: 0.02 s, total: 0.03 s
Wall time: 1.42 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: 0.04 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: 0.04 s
1/4*x^4
}}}
On the Power G5 with the new Maxima:
{{{
sage: time integrate(x^3,x)
CPU times: user 0.04 s, sys: 0.06 s, total: 0.10 s
Wall time: 4.04 s
1/4*x^4
sage: time integrate(x^3,x)
CPU times: user 0.02 s, sys: 0.00 s, total: 0.02 s
Wall time: 0.03 s
1/4*x^4
sage: time integrate(x^3,x)
CPU times: user 0.02 s, sys: 0.01 s, total: 0.03 s
Wall time: 0.04 s
1/4*x^4
}}}
and the old Maxima:
{{{
age: time integrate(x^3,x)
CPU times: user 0.04 s, sys: 0.07 s, total: 0.10 s
Wall time: 4.87 s
1/4*x^4
sage: time integrate(x^3,x)
CPU times: user 0.02 s, sys: 0.00 s, total: 0.02 s
Wall time: 0.04 s
1/4*x^4
sage: time integrate(x^3,x)
CPU times: user 0.02 s, sys: 0.01 s, total: 0.03 s
Wall time: 0.04 s
1/4*x^4
}}}
So it was actually faster with the new one.
I managed to update Ecl and Maxima on top of sage 4.5.1 on a Sunblade 1500
(SPARC with Solaris 10), but doctesting maxima.py timedout or died eating
all the memory.
