Ok.
I'm done with tracking.
It's right inside gtk_text_buffer_insert
Postponing the investigation of this due to it's level of difficulty
compared to other matters at hand.
I am 95% sure it's gtk+ problem. What makes me wonder is that google
doesn't seem to know anything about it.
It does all sorts of things inside _gtk_text_btree_insert for some
reason.

Meanwhile Mahogany can be made usable with the text viewer by:

* Making it not process the text twice in some occasions
* Calling wxTextCtrl::AppendText as less as possibly, that is it
shouldn't be called once for each line if lines have the same style
really, but only once per _real_ style change.
With the sample message I was sent should then render at least 50 times
quicker, most probably more.
Without the Quotes and URL filter the message is written with just some
AppendText's. With the filter turned on, at least once per line.
* Alternatively even better instead of the previous point is to write
all and then style it with SetStyle. See below.

Each AppendText call costs some time in milliseconds, starting from zero
and raising gradually when called on a larger buffer. In case of the
sample message I was sent, maxing out at around 90 milliseconds. The

 Hello,

 thanks a lot for taking time to look into this, and really sorry for
having no time at all to do anything myself right now...

MR> Meanwhile Mahogany can be made usable with the text viewer by:

 I'll look into this but it seems that even when it processes it only once
it is still way too slow (50s to show the message!?).

MR> shouldn't be called once for each line if lines have the same style

 This makes a lot of sense and should be easy to do... I'll do it, Nerijus,
could you please test if this improves things enough to become usable?

 This will unfortunately require some heavy changes.

 Thanks again,

Yes, now 15 seconds, thanks! But still much slower than gtk1 of course.

Hello,

M uses a lot of USE_PCH and only a few WX_PRECOMP. Why?
Wouldn't using only WX_PRECOMP be enough?

repeated function make error.

Greetings,

I have worked through a problem or two already and am faced by a situation 
arising from multiple definitions of the same function in two different 
source files.

As you can see from the output this is happening with ParseColourString and 
GetColourByName. I looked in the files with the GetColourByName definitions 
and and one appears to be a file that came with the source and the other 
appears to be a file generated at runtime by the make procedure. I am 
guessing I need to comment out the make generated definition, correct?

BTW I am running on Slackware 9.0 and have the latest successful build 
snapshot for the Mahogany source.

 Hello,

 which file is generated by make? Normally miscutil.cpp shouldn't exist at
all any longer -- the few functions from it were moved to other files (in
particular ColourNames.cpp). If you have this file in the source tree, it
must be a [mix of newer and] older version, please remove it. If it's
somehow generated during make, I'd like to know how does it happen...

 Thanks,
VZ
