WaitAliasChild taking minutes when Object does not exist

Question

I am trying to use WaitAliasChild to check whether an object exists or not. When it does exist it finds its normally and quickly. However when it does not exist it seems to take around 2 minutes to resolve saying it is waiting for the object regardless of what timeout time I put into it. I know the parent object that I'm calling it on does exist at the time of it running, and the child I'm looking for is also a direct child, but I'm not sure why it would take so long. Is there a reason for this that I might not be seeing?

here is the feedback i've gotten (disclaimer, not my words)&nbsp;okin&nbsp;Marsha_R&nbsp;
------------------------------------------------------------------------
How the waitXXX methods work: they try to find object on some level during the timeout, if they have spare time left from timeout, they make one more loop.So, if timeout 1 minute, but for compare all object with properties on that level consume 30 sec. it will have 2 iterations before say that there is no such object (30 * 2 = 1 min). But if user asks TC to wait only 10 sec/&nbsp;it still need to check the object at least once, so it will be 30 sec.But the question is why it consumes 2 minutes in user example.What we can suggest:

Put intermediate levels into NameMapping tree (remap object with additional levels) (Aliases structure can be the same, only NameMapping tree is important for performance). Ideally to find closest stable and meaningful&nbsp;parent&nbsp;object&nbsp; and perform WaitAliasChild from it
Optimize the properties set (it's most difficult and non-trivial thing)
Remove the object inside NameMapping (! not Aliases) tree, and remap it via new "Map the object using CSS and Xpath selectors"&nbsp;

Have you tried these two wait times?&nbsp; What happens then?

I've tried both, no matter what time I put it still takes a little over 2 minutes. Even with -1 supposed to be setting it to the default wait time which is 10 seconds in my case.

Also after some more testing it seems to take around 45 seconds in Internet Explorer (while the 2ish minutes happens in Chrome). Also the wait time does seem to have an affect but only if you make it longer than those times and even then it seems to be a bit off.

I remember having this happen at my previous job but I don't remember what we did to fix it.&nbsp;&nbsp;🤔
