Loads are now almost always >0.00 and sometimes touching 0.10 The changes to the load average calculation only added jitter to the timing of samples; the algorithm used to compute the load average from the samples is still the same. Could you post a `top' screen shot from the server in question? (make sure to leave top running for long enough to get the %idle etc lines filled in). Is it possible that the processes spend the vast majority of the time sleeping in select(), but that previously their run periods were often synchronised with the samples used to calculate the load average, or maybe it was system processes such as bufdaemon whose run period was synchronised with the samples? If so, then maybe the old loads around 2.0 were simply wrong. In general the %idle figure in top should be close to 100% if the load is close to 0, so that is worth checking too.
