I don't know what would be a good reason for wanting X to work nicely with a make -j25 running. X typically needs at least 75% CPU on my box to be nicely interactive when moving a window or scrolling something complex. This gives only 1% to each cc1. I am still working on my scheduler. I've removed backboost. It is hypocritical of me to worry about complexity or difficult traceability of say Con's implementation when backboost is probably "worse" than anything he has ;) So I've found I'm getting more consistent behaviour, but it is now very dependant on nice to get X running well under load. I'm concentrating on getting it working well with make -j <= 6. - 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/
