This is with i24 l30 in make.conf. How many cores does your CPU have. I've found that load is an approximation to "how many cores are running at 100%". It's very noticeable running xosview, that as soon as load goes above 4 on my 4-core system, response goes through the floor. Which is probably because a large chunk of CPU time suddenly gets diverted to scheduling and task switching, rather than doing useful work. Cheers, Wol
