It does not have enough space to be useful for much else. So I decided to test the low end and tried it with 2.5.42-mm2. It boots and seems to work fine. Then I tried the resp1 (http://pages.prodigy.net/davidsen/) benchmark. With 2.4.18 it works: Memory size 61 MB Starting 1 CPU run with 61 MB RAM, minimum 5 data points at 20 sec intervals . . . . . . . . _____________ delay ms. ____________ Test low high median average S.D. ratio noload 2128.527 2138.035 2129.915 2131.269 0.003 1.000 smallwrite 4178.129 27436.634 4318.342 11111.745 8.927 5.214 largewrite 4157.574 78592.200 4222.064 16336.681 24.926 7.665 cpuload 6109.576 8018.156 6230.810 6425.307 0.600 3.015 spawnload 5508.218 6934.219 5556.992 5706.077 0.462 2.677 8ctx-mem 10090.974 22222.700 12662.532 13511.634 3.433 6.340 2ctx-mem 9330.010 21106.194 10745.474 11650.974 3.612 5.467 with 2.5.42-mm2 it does not finish. The machine is sort of usable while its runing and control C has no problem ending the program. I waited 11 hours for the spawnload test to complete - it was looking very good before this....

About 25% User and 75% system in cpu though. Ed -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
