yes, a slow movement to in code cleanup and reorg to make things a bit faster.

yikes, 128 is VERY restrictive.  check your swap usage, a server should never 
swap
more than about 20 meg.

apache2+php isn't as stable as apache would lke you to believe, ask the php devs

cache's will decrease latency, but increase memory usage, and you have very 
little
memory to start with so it's gonna swap and increase latency even more.

what are these other apps?  message boards?  a site content manager?  phpgw is 1
bazillion times more complex than that.  it is a message board, AND a content
manager, AND a calendar, AND an email app... you're not doing a fair 
compairison.

definatly memory starvage.  posts have to allocate enough memory for php to 
parse
the header, then store that for the script to access, then run the script.  if
you're in swap, you're screwed.

yes, but only for certain reasons like having a firewall and configuring phpgw 
to
get NTP over a port that's blocked.

Mine runs a little slow, but it's an older distro on a 2.2 series kernel and 
only
256Meg ram (and swapping) on a celery 300.  But it's not unbearably slow, and I 
know
I have minimal hardawre, even message boards don't run all that fast on it.

check swap usage, consider adding 512Meg RAM.  I give my low end users 128Meg,
managers 256, CAD guys 512, and me a gig.  You're only giving your server 
128Meg?
that's "minimum requirments" for a web server, you should expect it to be slow.
