Clearing cache is really sloooowww

[Jacques Le Roux]

Hi,

I don't know if some of you have tried to clear caches these last times, but it's now very, very, very slow... (more than 10 times,
maybe even more than 100x...)

Is this after the last set of changes I *just* did?

Note, that if you clear caches from webtools, the caches will clear
fast, but then it has to reload a bunch of data again; it's this that
can be slow.

In any event, I just tried clearing all caches, and it appears to run
fast.

Yes I think so, but I just saw that you did some changes in util/cache are they related to this message ?

I did not look at details yet

Surprised, I tried on 2 local instances : same symptom.

I will update your last changes, anyway...

Unrelated.  I was just backporting changes from head to
our(brainfood's) local package, and noticed some synchronized blocks
that could be removed(I've converted a bunch of stuff in UtilCache to
be non-blocking/unsynchronized).

On my local copy I'm seeing thousands of entitycache entries, each with
only one item cached.

That was what I needed to fix it.

When I tested it after Jacques noted the problem, I went to webtools
immediately after starting, so it only had a small list of entries.

I've fixed this in 884262.
