Yup. Adding 7 extra void*'s seems to affect only dbench, which whose degration with the nsproxy falls outside the noise. The odd thing isn't so much the degradation, but the widely scattered values, compared to without nsproxy. | with nsproxy | without nsproxy | kernbench | 70.23 +/- 0.27 | 70.04 +/- 0.22 | dbench | 367.1 +/- 32.6 | 410.0 +/- 2.96 | tbench | 399.3 +/- 12.4 | 399.4 +/- 12.5 | reaim with nsproxy 1 115600.000000 5512.441557 3 243099.998000 10876.225044 5 270002.798667 11800.545221 7 283291.578667 10897.147984 9 294530.528000 7095.760045 11 nan nan 13 nan nan 15 nan nan reaim without nsproxy 1 114240.000000 5728.697311 3 254271.426000 11767.994417 5 279965.036000 12615.448140 7 281660.000000 9898.028733 9 302905.264000 5165.026561 11 nan nan 13 nan nan 15 nan nan - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
