Hi Robert, OK, mystery solved, I was using r9140. I've now updated to r9149. Sorry about that.
Now the results, using the original options verbatim, are: Machine: notebook Lenovo T61p, Ubuntu 8.04, Core2Duo 2.2GHz, 2GB ram + 2GB swap, nVidia Quadro FX 570M 256MB, driver 177.80. 1) only 99 in 17.7 seconds 2) only 198 in 4.9 seconds 3) only 1,477 in 2.1 seconds 4) all 10,000 in 4.9 seconds 5) all 10,000 in 1.5 seconds 6) all 10,000 in 7.9 seconds 7) only 215 in 1.8 seconds 8) only 237 in 7.8 seconds 9) only 239 in 58 seconds Test 7 killed the X11 server once.
