Re: [TSVN] Very long time to crawl WC.

Hi Stefan

I have decided to collate and clarify all the symptoms and end result
into one email.

----- sent before in "Very long time to crawl WC" and further clarified
----------
I have checked out a 115Mb WC which occupies 149 Mb of disk space.
Win2K and r5015. (NTFS partition) dual core 3Ghz processor.

The cache is crawling the resultant WC with very low CPU usage and
taking a very long time. > 1/2 hour
What may be contributing to the time taken is a batch of "Invalidating and
refreshing folder" messages that follow the writing of each folder full
of files. The
process eventually comes to an end, unlike the problem just fixed or
maybe partially fixed.

A screenshot of the cache window is attached. It's a midstream sample,
something I'm familiar with in another context. If you cannot replicate
thus and need further data gathering I'm available.

----------- sent in reply re 100%CPU and clarified ----------
Further observations are:-.

The difference between yesterday's r5002 behavior and todays r5015
behavior:-
is that the crawling does eventually get through the WC.

The problem is only occurring during checkout of a new WC, there is no
problem crawling the new WC once it has allarrived or WCs that have been
on the machine for months.

My recipe.
Nav to folder with a small old wc.
Observe the cache window crawl quickly.
Checkout a duplicate to another named WC.
See what happens in the cache window.
I see lots of Invalidate... messages and it finally is all checked out.
Browsing the recently checked out folder seems normal.

I have put the anti virus to sleep, disabled SpySweeper from starting
and removed the affected folders from Recovery Bin to minimize their
potential effects.

---------- New Info -----------

On deleting a fresh checkout it looks like the cache isn't releasing as
much memory as was acquired while crawling the new checkout.
On a subsequent checkout without rebooting, cache memory use is
initially stable then climbs past the total used during the previous
checkout of the same repo.

While deleting the big 149Mb WC a whole bunch of "Invalidating
...folder" messages were flowing too and cache memory used went up over
35Mb.
Finally the screen went blank and would only refresh where controls were
responding to mouseover type events.
Fortunately "Start" "Restart" were among them.

So, for big WCs this looks like a real problem.

Sorry, why is it always me?
