nYields in explain

[Vbabiy]

I know what nYields is, but I am trying to find out more information about what would cause a query to timesplit and cause a nyield?

It's a bit complex, yields are triggered by a certain number of
documents being traversed or a certain number of ms elapsing (like 10),
and then actual yield time (could be zero) depends on the other cursors
open.

Does it take all cursor in to algorithm or is it only the cursors that
are working in the same collection? Also is are there any
recommendation to get around this?

It takes into account all waiting clients for the db... but I wouldn't
depend on this behavior in the future -

I'm not sure what you mean by "get around this," are you running into a
problem of some kind?
