after upgrading to .19700 i have the same problem with very very slow adding to cart!
Didn’t have this problem before....so i don’t think it’s caused by the DB!!
I have the same problem on my installation.
I have installed APC and i noticed much better speed performance but
when i click Add to cart or My Cart it takes about 20 sec to get result
The problem seams to bee in acces to app folder
according to information from my profiler it seams to be problem with acces to app folder
it takes about 20 sec in my case

I guess that also rules out your hosting, since you didnt have that problem before, just like a few others here, In my case the problem has been there since day one, tried just about everything, even a local machine.
I had a very similar issue. Whole shop was really unresponsive, cart manipulation being especially slow—any operation took more or less 30(!) seconds. Inadequate computing power was out of question—this was on a dedicated dual-core Xeon server.
Profiling the application with Xdebug showed that massive amount of time was spent on fclose() calls. I’ve seen 1506(!) fclose() calls in one request. The Zend_Cache_Backend_File and XFS filesystem obviously did not go very well together. Moving the cache directory to a tmpfs volume reduced the time needed for cart operations tenfold.
It would be really useful if the Zend_Cache_Backend_Memcached or Zend_Cache_Backend_APC could be used instead.
Anyone experiencing similar issues, try checking the filesystem your cache is on and moving it someplace else.
prefix should be unique for each Magento installation, if you have multiple ones.
It is strongly recommended to upgrade to 1.0.19870 as a few non-file cache backend bugs were fixed there.
it seems that add to cart from grid view is more fast then view product page
Are you addnig up all the values in the Time column, or just looking at the value for App? You need to add all of the values up to get the full page load time.
Remember though, the profiler actually adds time to how long a page loads, normally the store loads (at least for me when I ran this test) up a second faster, and then add to cart 2-3 seconds less.
There is definitely something up with the new version. I have an older version(1.0.19870) of magento installed on one site and can use it with no problems at all. I just installed the newest version and am getting roughly 30 seconds for cart additions, etc. The host on the ladder is actually faster and better than the host on the former. Plus, the wiki, and wordpress that is on ladder performs just as fast as on the former so it’s not the database.
The worst part is, whatever is taking so long with the checkout process.....is making the payment module extension I created not work correctly (not a single file from the extension changed from one server to the next, both were clean installed from magento-connect). It works great on the old version of magento.
You guys really need to take a look and find out what is going on.
I did notice that when I try and drop the tables to clear out the database (putting the old version on the other server for testing), it errors on the table eav_attribute_set. I have to run the drop tables query 4 times to clear out all the tables. So there could be some issue there that is causing everyones page loads take long time when it tries to query something from that table.
How does it affect the performance, if you disable EAV cache?
Wow, I just tried disabling that and the site is smoking fast now. Well, not really, but it is taking about half as long to load stuff overall (so about 3 seconds max including checkout pages, 1.5 seconds for overall site average)
What is EAV cache and what is the benefit of having it enabled?
edit: I read up on it, and it seems to have to do with database structuring. If its faster to have it off, is there any downside, like increased traffic usage, or anything?
It works great on the old version of magento.
