My systems become unstable, if I use VIRTUALADDRESSLIMIT above 2560. I did run your script, and rebooted.

After reboot, Above512 shows (in KB) low private mmemory: 357120, low shared memory: 270592, upper private memory: 1835008, upper shared memory: 1814144. After starting Dooble, it shows low private mmemory: 305536, low shared memory: 208000, upper private memory: 1713728, upper shared memory: 684116.

From that, it appears that VIRTUALADDRESSLIMIT=2560 is sufficient (but other things could use more upper shared memory than what is left). There is no hope that this would even get off the ground, without at least 1.2 GB of upper shared memory available. Then, it seems to eat more upper shared memory, as it is used. Lower shared memory, and private memory, seems to be adequate.

Of course, this is a very rough estimate of these numbers, and different user setups can change the numbers.

I wonder if a TURBO is needed, to keep DLLs loaded in high memory, without unloading them. It would likely help startup speed too.

I have to ask if this is supposed to work with my Ryzen Gen 3 processor system before I mess with a now working system.

Dave Yeo:
Hi Ivan, why wouldn't it work with an i386 with SSE2 compatible processor? Pentium 4 is a crappy architecture for most of us but shouldn't be worse for your AMD then my I5.
I have asked Bitwise to tune for generic which will help all of us.

Hi Doug, yes, it seems 2560 is good enough and if that's the highest that is stable, well stick with it.
As for a turbo program, it was mostly needed to work around a kernel bug that didn't properly release high memory, now fixed in ArcaOS, still be handy for older kernels and as you mention, probably speed up loading. Help with memory fragmentation too, which will bite us after starting and stopping programs enough times.
Remy developed a general purpose turbo program which took a list of DLLs, might be worth checking out.

I don't have one, so I can't say, for sure, but it is running better than I expected, on every machine that I have installed to See other posts about some operational problems (nothing really serious):
Asus A88XM-A, with A6 processor.
Asus M3A78-EM with quad core Phenom processor.
Lenovo ThinkPad L530 (Intel I5).
Lenovo ThinkPad T510 (Intel I5).
Dell Optiplex GX270, with a single processor. I have 3 GB of memory, and 1 GB is allocated to a RAMDISK. (I am posting from this one). It seems to get very slow, when some other program is running, but by itself, there isn't much difference in performance.

If you have a reasonable configuration, properly installed, with the Pentium4 platform configured for RPM/YUM, it should work. Note, that you can run Dooble alongside of Firefox, even at the same time. There is very little, if any interferrence. I expect that T'Bird, and Seamonkey, would be much the same. Be aware, that running then together can easily fragment upper shared memory space.

Of course, it is always a good idea to have a good backup.

Hi.All.
It can be used immediately after installation, but once it is closed, it will not be able to connect to the Internet.
