I think the term 'reimplementation' would describe better than 'port' what was and will be done :-)

It works OK for me, I've had no issues using it. In any case IMHO v1.25 of OWB (v3.11 of MorphOS release) is a great step forward from v1.24 (MorphOS v3.10).

Anyone likely to do, or know the benchmark between the v1.25 MorphOS v3.11 release of OWB, and of this JIT enabled ßeta released version for any improvement in speed or RAM performance, i.e. more efficient use of memory, &/or of it not causing fewer memory leaks that lead to low memory conditions.

From my rudimentary testing of it, I'd say it seems better using memory, as I don't seem to be having the same lack of memory after the same amount of use/number of websites visited.

BTW. I did try to use the latest OWB 1.24 from Fab's site (not these newer MorphOS included ones) and oh boy that consumed memory a lot faster on big gossip pages :) Couldn't even browse one page through before all memory was used (1GB machine), while I can do that and go to other pages with these newer ones. So memory usage has clearly been improved even if you don't notice it that easily when going to the better direction :)

I don't have any personal feelings of "faster" or "slower" than the non-JIT version, but so far the benchmarks results suggest that the JIT-enabled version it's generally slower then its predcessor:

For me it feels the same. I have not seen any difference so far. Which typical websites should be faster or slower? I did not realize any differences in news pages, PayPal (still not possible to make a money transfer and the same timeouts), mail provider pages.

Unfortunately it seems that I managed to accidentally leave out a specific (and important) optimisation from this release. I've uploaded a new OWB-JIT archive to my website which has this optimisation re-enabled :)

@koszer
Thanks for pointing this out :) With the new binary, Sunspider still doesn't show a great improvement, but an improvement nonetheless, at least for me. Octane shows a much nicer improvement, but has its own issues as the "pdf.js" test runs out of memory. The tests before then show up to a 3 times improvement for me.

Please download the new binary and try again, and if you find anything that else that doesn't seem right, please let me know!

To verify that you have the updated version, the update OWB-JIT.lha archive has an md5sum of1bfd40216a4abf9c13b228a9227dfed4 and the updated OWB-JIT binary has an md5sum of0f3ba9ce5a086748b4a9737be3150cff

The thing I know for sure is that Mark himself is faster than his OWB-JIT
Mac mini G4@1,5GHz silent upgrade + Xerox Phaser 3140 + EPSON Perfection 1240U
Commodore C64C + 2 x 1541II + Datasette + SD-Box

I miss draggable screens... and do you? I know I'm in a minority unfortunately.

I've tried Octane 2.0 benchmark on a 1 GB RAM equipped iBook G4 1,33 GHz and without JIT it passes the test (with 358 points AFAIR), but with JIT enabled the browser hangs halfway (the memory gauge suddenly goes 100% and bam - it's meditating).

Make sure you update to the second release I made. Also, the JIT will only make some things faster. It will not change anything for things that didn't work at all before.

Yes, as mentioned the pdf.js test runs out of memroy. I have not yet investigated this issue, so I don't know if it is because of a bug or if the JIT version simply uses more memory, but it's probably a bug. I also found out that one of the later tests fails with JIT as well.

I've uploaded two variants of the Octane benchmark to my website, first one that disables the tests that fail with the original OWB (zlib test) as well as the two tests that currently fail with JIT (pdf.js, Mandreel) and then also one that also disables the regular expression test, as the regular expression JIT is not yet enabled.

OWB-JIT does not handle timezone information.

getTimezoneOffset() returns 0 but should return -120
getUTCHours() returns the same value as getHours()

In OWB included in MOS 3.11 it works fine.

I cannot log in to my Adobe ID / amend/request a new password - OWB/CPU just goes into "overdrive" and nothing happens, the mouse cursor continues to be moveable, and screen swapping works OK, but the OWB window/program takes over the CPU and it ends up running at 98-99% activity, wit nothing happening for minutes on end, so I felt it required a warm reboot to start again, that's with OWB v1.25 either the v3.11 release or this later JIT enabled version.

I also cannot log into the ITV (Television) Hub to type in the "Date Of Birth" input request area as the cursor won't go active in that field, so I had to use a "Windows" browser to be able to activate access to this ITV Hub, which I was loathed to do, but I couldn't find a way to accomplish it with OWB, as even spoofing didn't work.
