code completion very slow [message #104319]

Hi!
My Code Completion is very slow. For example I want to write the method
"main" (a code template included in CDT 2.0 M09: i type ma , then ctrl +
space. It takes at least 5 seconds until the code templates show up.
(i have included <iostream>; without it it works normal)
i have a XP2400+ with 512 MB RAM! Shouldn't it work faster??
Is there a way I could speed that process up??
Otherwise it would be nearly useless for me because in 5 sec i have
typed it all by myself.

Thanks in advance

PS.: I'm sorry that my english is that bad :-)

We are working at trying to make the parse faster.
There are numerous defects open on Search and Content Assist wrt memory
consumption and performance that we plan to address in the next few weeks.

A short term solution that you could try while stuff get fixed properly by the
CDT team is that if you're using SUN's JVM, try using JRockit instead:

http://download2.bea.com/pub/jrockit/142/jrockit-j2sdk1.4.2_ 03-linux32.bin
http://download2.bea.com/pub/jrockit/142/jrockit-j2sdk1.4.2_ 03-win32.exe

I can't say anything about the performance of Eclipse on JRockit specifically
(you'll have to judge that yourself), but in general JRockit tends to outperform
SUN's JVM.

Stability wise I'm running Eclipse (2.1.3 though and no CDT) on top of the above
JRockit release and I'm not having any problems. Of course this doesn't mean
you won't, but at least in theory it should work well.

Full disclosure: I work at BEA and am probably biased.

I use JRockit with the CDT. It's faster but marginally so. And it's no

of. It's very encouraging to hear that the CDT team will address these
problems in the coming weeks. IMHO, it should have top prio. It's really
impeding more extensive use of the CDT.

Kind regards,

We hear you and it is certainly our conclusion as well. The good news is
that there appears to be a lot of things we can do to make the parser faster
and smaller. It should just be a matter of time until we get there. It is
certainly my number one priority.
