Re: Slow down, latest updates

[Dr . Jürgen Sauermann]

Hi Bill,

I cannot reproduce this.

Did you run ./configure after updating from SVN? Sometimes Makefiles slip
through and can cause performance differences that are then caused by differering
 ./configure options. I normally use make develop which turns many debug
features on which are turned off when using the default ./configure options.

I have changed your benchmark a little to show the time spent:

∇rr←sol nn;T
T←⎕TS
n←1↓⍳nn
r←,2
l:
→(nn<(↑n)*2)⍴x
r←r,↑n←(~∨⌿0=⊃r|¨⊂n)/n
→l
x:
r←r,1↓n
rr←+/r
0.001×0 0 0 24 60 60 1000⊥⎕TS-T

For the last updates, my little test program has slowed down by a factor of more than 4, debian 32 and 64 bit.  (Same updates as the compiler problem appeared, I think.)
