NetSurf OS3.x Issues

[utri007]

I was getting weirdness until I switched friend bitmaps back off.

I have fixed some other bugs in the meantime though.

I turned OFF backgroung and foreground images and it seems to work. So it is images wich make those problems with AGA.

Acill: I  have tested arthurs version only with real amigas, there is no speed difference. I didn't know that there is a diffrence under the emulation.

Arthur's RTG version is running top of SDL and AGA version is running Novacoder's AGA SDL hack. It is based to framebuffer version of Netsurf wich is meant to be used debugging and with "no gui" systems.  

Chris version is based to ordinary desktop version. He has some problems with GCC version he is using, he can't compile it optimications turned ON.

I think that I found a reason for some problems.

AmiTCP/Genesis has maximum ram usage set to 256kb and buffers to 8092

I increased ram limit to 1024kb and buffers to 20000. After that I couldn't "kill" my Network. Also surfing from amigaworld.net to amiga.org took only 45 seconds. But surfing back to amigaworld.net took some 100 seconds and repeating it took more than 200 seconds.

Same thing with miami and I'm prety sure that Roadshow has those limits also. Because Oldsmobile_mike uses it and has also suffering Network lockups.

I have bought Roadshow and I spend some time installing it, but I couldn't get DHCP working, so I decided forget it. I'm familiar with Genesis and DHCP would have been one advantage over Genesis.

AmiTCP log has lots of memory and buffer errors. This problem doesn't exist with AWeb or IBrowse.

Acil: Seems that A4000 users has some difference to A1200 and A2000 users.


Edit :

max_fetchers:12
max_fetchers_per_host:2
max_cached_fetch_handles:3

Didn't help, it does little slowdown, nothing more.

I tested this under emulation, most noticeable thing is that there is no Network slow down when surfing. Even login to amiga.org was fast. Got this error after login :

Assertion of condition "perror == parseutils_ok" failed in file "utils/utf8.c", line 135

Problems with amiga tcp/ip software would be logical explanation for that. There is no Network problems even with cycle exact emultion, UAE uses it own Network.

Also there is a big difference compared to Arthur's port, it is indeed much faster under emulation, but not with real amigas.

[utri007]

I've managed to reproduce this finally, and I think it's because of the GIF anim that sometimes appears on the aw.net header.

Try:
animate_images:0

Didn't help. Problem has nothong to do with amigaworld.net. It just basicly first page loads fast, second one loads about 2x longer than it should, third about 4x longer etc.

It even happens if I go to amiga.org forum or any other page.

I don't know is this some sort of TCP/IP stack problem or not, but I loaded some pages from local hard drive and there was no slow down when changin page. I add 4x memory to genesis 1024kb and increased send / receive buffres to 16184, that didn't help either. Though no memory / buffer erros anymore and it doesn't die if I left Netsurf open for some time.

I made some testing more. Yesterday I browsed some pages from CU-Amiga CD, no slowdown at all. Yesterday just before I went to sleep, I found this site from another thread here http://www.amigahistory.co.uk

That is hard to find site, it pure HTML, build with tables. No CSS or Java. Prety much like those www sites from CU-Amiga CD. It is displayed right even with iBrowse.

No slow down at all, every page loaded same time 10-34 seconds. Could it be possible make a conclusion that TCP/IP is not a problem?

[utri007]

I don't know about memory requirements, because clib version doesn't start any of my systems. Other versions requires at least 24 mb ram, they doesn't start my 040/32mb system becuase lack of memory.

Another thing is that Arthur version is very stable and fast with emulated amigas. There is no real speed diffrence with real amigas, execpt Chris version is much more stable.

Memory fragmention would be one logical explanation, but I'm usually running this on my startup-sequence. http://aminet.net/package/util/sys/PoolMem

It doesn't have any effect to Chris' Netsurf decreasing speed, is it running or not. Memory framention can be monitored any way.

[utri007]

My 060 has plenty of free ram when surfing amiga.org/amigaworld.net, so memory allocator should be broken, if it fragments memory with them. Another thing is that at least amitcp and miami has limis for ram usage, could it be that that memory is fragemted? AmiTCP has 256kb limit as a default for ram usage. Setting limit 4x higher 1024kb doesn't have any effect to speed decrease.

Preferences do work. One note, it is not actually preferences, but I can disable images, but I can't enable them back on.

You have spend some time with aga? It works/displays right again, but 4/5 times it goes unresbonsive before it it displays anything. This with my 68040/AGA

My RTG amiga has wrong colours, usually it is fixed with friend bitmap, but this time it doesn't have any effect.

About increasing download/fetching/rendering time. Downloading amiga.org takes now 27 seconds, going to forums takes 55 seconds, downloading amiga.org frontpage again tooks 129 seconds.

Log file is too big, even in zipped to this forum. Send to your email.

I can't see anything wrong with that code.  All it does is check the state of the menus and then set the images options so they match.



I've only been testing with AGA, can't help with the wrong colours thing, I'm not set up anywhere to test it.  I'd hazard a guess it's to do with the endianness of the screenmode, I've not changed anything related to colours or friend bitmaps AFAIR.

Bit off topic :
I reinstalled myt amiga some days ago. I can't remember did colors work after that or not. But I have a 15bit PC, 16BIT PC and 24bit PC screenmodes availlable. I'm using Picasso 96. Do I have setup problem or not, sorry my ignorance.

What about TLSFMem, does it improve speed a little?

Netsurf starts and loads wellcome screen, but locks Computer after 10-15 seconds when trying to surf any other web address, if tlsfmem or tlsfmempool is running.

[utri007]

The PC modes are little-endian, so that may be the problem.  It's likely I have some code which is assuming the screen is big-endian.  Does text show up the correct colour?  I know for sure that uses pen allocation so I'd expect it to.  Bitmap plotting is somewhat more involved.

I had excatly same hardware and picasso96 earlier also. I wonder did I had 15bit RGB and 16bit RGB modes earlier. Need to figure out why they have disappeared. Any hints for that?

Really can't say anything about text color, at least colors are not obiviously wrong.

[utri007]

Checked this with snoopdos, it says Fonts:helvetica.font. Should it be just helvetica.font, if it is preloaded? Any way

On thing wich took a lots of time is Ramlib open ENV:Gadgets/select.prefs

Need to spend some more time with this.

[utri007]

Possibly.  Are you looking at Open, OpenDiskFont or OpenFont?

All font things on snoopdos are Open FONTS:helvetica.font  Read

I thought that I found some kind of pattern, but I'm not sure. First time when loading amiga.org there are only some ChangeDir, seems that number of them increases when going to forums and even more when going back to FrontPage.?  ChangeDir can take several tens of sceonds.

Weird thing was also that ramlib Load Libs:Gadgets/select.gadget, it should be Classes:Gadgets/select.gadget? Would it be because of netsurf?

[utri007]

I'm a curious what is changed this new version?

Is it so that aminet release link is wrong, it goes here, it says OS4 version : http://www.netsurf-browser.org/downloads/amiga/

[utri007]

New typo All the downloads are gone in netsurf page.
