| Quanta using 90%+ CPU |

2007-07-20 09:48:50 |
Hello!
I did not use Quanta for a while but recently, i.e. I think
with the update to
3.5.7, I get it using 90%+ CPU for an increasing amount of
time. The longer I
edit files, the longer the "pauses" become.
They happen after adding text to a file, no matter whether
it is a CSS or PHP
file. I disabled the highlighting which did not help. I use
a 1.4GHz CPU with
1.5 GB of RAM, so editing files with ~1000 lines of PHP code
should not be an
issue.
I have no clue what else I could disable to work around that
bug or what is
causing it. It also happens when I close or open a file.
After 15 minutes I
cannot work with Quanta anymore since every pause lasts up
to 15-20 seconds.
After restarting Quanta editing the same files works
perfectly, until the
pauses start to kick in again.
Anyone else experiencing this?
Sven

A number of people have posted these issues here in the
past. The usual
response is: we are aware of the issue. I've certainly
experienced the
issue myself as well.

I am not a Quanta coder, but might it not be useful, to do a
strace on quanta
when it pauses, and then emailing that to the developers?
strace is not
perfect but it has saved me tons of times in the past.

Yeah, I am experiencing something similar. I have my
projects on NFS share. If
I do strace -f -p `pidof quanta` during slowdown I can see
it opening and
reading beginnings of random project files. This question
comes up on this
list from time to time and so far there is solution for it.

Yes. I'm getting the same thing with 3.5.7.

I had issues before where quanta did take a long time when
editing files, but
that was 2-3 seconds and the time it paused did not
increase. Thus I asked.
For me this is a new issue and different from the
"normal" stalls that happen
when editing files.
I'll try to run strace as suggested by somebody else. Is
there any chance that
quanta will get back to the "normal" slowliness
soon?

Yes, and unfortunately it is (very) hard to fix... Just like
some random
crashes.
Usually such slowness might appear when you have lot of { }
structures
in your file or there is some error in your file which
"stresses" the
parser, because it tries to parse eg. as PHP code which is
not PHP or
something like that.
Usually an example file and a way to reproduce the behavior
raises the
chance to find the bug.

Yeah, another problem can be if you have many include
statements. Still,
example is needed.

Just for curiosity, did you experienced the same bug with
earlier 3.5.x
releases?

No. I've never had this happen before.
