[TYPO3-english] Typo3 4.5.3 intranet relaunch, what else should I consider?

[Floy Mark (LEWISHAM HEALTHCARE NHS TRUST)]

Thanks for your thoughts Oliver.

Tough break with that bulb, guess I'm just looking for any suggestions coming out of past experience...

Our project board discussed bringing in an external consultant, but decided it would take too long for a re-launch as user anticipation is pretty high.

Caching, MemcacheD did not give me the benefits I expected, had to reverse it out in the end.

Are there any specific Apache modules I could probably discard?

At the start of the project we installed the DB and Web functions onto distinct machines on our virtual environment.


Regards,
Mark

Hey Mark,

my glasbulb is broken right now. :-)

you might want to hire some experts to analyse your setup.

my experiences tell me:

* bad or no caching settings on all app layers
* bloated apache settings
* mysql and apache on the same host eating up their memory

best regards,

olivier
