[TYPO3-performance] TYPO3 4.3 performance

[Dan Osipov]

For the first test, were you using DB for cache? How many other entries 
were there in cache?

I was looking at the tags field, and it seems that functions like 
flushByTag will take a long time on a large cache. Could a full text 
search index be added to that field to improve performance? Has anyone 
tried to use a large cache on memcached?
