This page needs to decide if it is about unix (& clones) load averages, or about the concept of computer load. There isn't currently a page about unix load averages, and most of the unix related stuff here is reasonable enough to start one. The windows section needs to be expanded or explained. The "Other Meanings" section would probably be better shifted to their respective pages, or made into separate stub pages. --[[User:CalPaterson|CalPaterson]] ([[User talk:CalPaterson|talk]]) 15:29, 4 May 2008 (UTC)

:The windows section needs deleted, really. Windows has no use for load averages. [[Special:Contributions/89.240.240.107|89.240.240.107]] ([[User talk:89.240.240.107|talk]]) 13:19, 12 May 2008 (UTC)

== "Load average is not CPU utilization" Section ==

I just removed a section titled "Load average is not CPU utilization" added by [[User:Sp0|Sp0]] a few months ago. The text of the section was:

: Even though the statements in the previous section might suggest that load average is related to CPU utilization because the section relates CPU to load average, load average does not measure CPU utilization of processes. One reason it does not do this is because load averages computations of processes are in a wrong order to relate to trend information of CPU utilization. In other words, the calculations and numbers directly produced by load averages do not compute numbers in an order from more CPU intensive to less CPU intensive or vice versa, nor do they give computations of numbers that would give another way that would result in direct information about CPU utilization. In summary, the functions of load average give numbers based on load queue of processes. <ref name="Empirical load"></ref> The next section uses the same reference to suggest that load average is not very important or vital to system performance information until or unless the a system's CPU is heavily loaded to around 100%. Then, at levels close to 100%, load average could be very important or significant to determinacy of system performance; however, this would be because average load numbers give direct information about process queue length not CPU utilization -- which is something they do not give direct information about.

Without making any comment on the accuracy of this information, there are two severe problems with this: First, it is almost completely incomprehensible due to grammatical errors and a generally rambling style. Second, the section existed to contradict the rest of the article. Sp0, if you believe the article is factually inaccurate, the correct response is to edit or replace the existing text to make it accurate, and preferably also to include citations of reliable sources to prevent an edit war. -- [[User:Tyler McHenry|Tyler]] ([[User talk:Tyler McHenry|talk]]) 18:24, 8 January 2010 (UTC)
