Hi Allard,

for 1CPU engines, would Spark 0.3 still be expected to have an edge over this latest Bright?

Cheers,
Graham.

I think so, yes.
But you'd better tell me :)

Hi Allard,
downloadlink for spark0.3a/bright0.5c does not appear in Firefox 3.5.7 :-(

Bright has a better understanding of "Open Files and Diagonals", and "Re-Capturing" than Spark.

Now works with firefox too.

Another Question: why is the difference (in bytes) so big ?
spark-0.3a-vc64.exe ........... 366.592
spark-0.3a-vc64-mp.exe .. 3.251.200

spark-0.3a-gcc64.exe .........221.184
spark-0.3a-gcc64-mp.exe .. 229.376 is similar

Bright 05a (with 1cpu) got a slightly higher score than
Spark 03a (with 2cpu).

Very interesting comparison, indeed.

Best,

Bright 0.5c used 2 CPU's in STS tests, so does Spark. (Read the conditions)

Perhaps I should now test gcc compile for Spark to see if it gets significantly better scores.
