Matrix efficiency in 1.9.0 vs 1.8.1
...ng on
integral operator models (implemented numerically via matrix operations)
and except for the way entries are generated, the examples below really are
representative of my problem sizes.
My main concern is speed of large dense matrix multiplication.
In R 1.8.1 (Windows2000 Professional, dual AthlonMP 2800)
> a=matrix(rnorm(2500*2500),2500,2500); v=rnorm(2500);
> system.time(a%*%v);
[1] 0.11 0.00 0.12 NA NA
In R 1.9.0, same platform:
> a=matrix(rnorm(2500*2500),2500,2500); v=rnorm(2500);
> system.time(a%*%v);
[1] 0.24 0.00 0.25 NA NA
These differences are consistent. But...

Revision 3.0"
[7] AMD''s 7th generation processors return a CPUID base
family value of ''7''. These include AMD Athlon, AthlonXP,
AthlonMP, and Duron.
[8] AMD''s 8th generation processors return an effective
CPUID family of ''0x0F''. These include AMD Opteron,

serious networking (em) performance (ggate and NFS) problem
Dear best guys,
I really love 5.3 in many ways but here're some unbelievable transfer rates,
after I went out and bought a pair of Intel GigaBit Ethernet Cards to solve
my performance problem (*laugh*):
(In short, see *** below)
Tests were done with two Intel GigaBit Ethernet cards (82547EI, 32bit PCI
Desktop adapter MT) connected directly without a switch/hub and "device
