Track arming performance (FIXED)

In our studio we just have a Pentium 4 (2.6GHz) machine. Arming 19 tracks (mono audio) at once is painfully slow. You see that the tracks get armed one by one. I didn't count the seconds it needs but I would say it takes about 4 second or so. Much too slow IMO. Any chance to improve the performance of this a bit? FIXED (3.05pre2)

Would be nice if we could collect some performance data here. Please post the time it needs on your machine to arm 19 tracks (mono audio input) at once in an empty (no plugins) project. Especially people with older machines should post their times. --------------------------------------------------- System: - Intel Desktop Board D865PERL - Intel Pentium 4 2.6GHz with Hyperthreading - Matrox G550 AGP 32MB - 3 Creamware PCI cards - 1536MB RAM - Windows XP Professional SP3 ASIO: - 1024 samples buffer - 20 inputs - 4 outputs - 48kHz samplerate Time to arm 19 tracks at once: ~4 seconds --------------------------------------------------- System: - Intel Desktop Board D975XBX2 - Intel Core 2 Duo 2.66GHz - Nvidia GeForce 7600GS PCIe - RME HDSP9632 PCI - 2048MB RAM - Windows XP Professional SP3 ASIO: - 256 samples buffer - 2 inputs - 6 outputs - 48kHz samplerate Time to arm 19 tracks at once: ~1 second

How do you arm multiple tracks at once?

OK, here goes... Dell GX270, P4 2.60GHz (hyperthreading), 3GB RAM Intel 82865G chipset Dux slipstreamed XP ASIO4all, 44100Hz, 32 bit 2/2ch 512spls ~13/13ms Record arm 19 empty tracks, mono SoundMAx Digital Audio 1, Reaper 2.53: instantaneous EDIT: Reaper 2.54, same time

Thanks - now I got an idea: On this Pentium 4 machine I was runnign Reaper from USB thumb drive. Could this be the reason? Of course I recorded to the local harddrive (peakcache also on local harddrive). But maybe Reaper is writing any other stuff on the USB drive!?

Thanks, just tried it on an Intel dual core (E5200 @ 3.5GHz). 19 tracks, instantaneous. Just an idea, could it be that what you're seeing is the slow graphics refresh? I remember being able to see GUI stuff being drawn on older computers. I see you use an old AGP card, could that be the culprit?

The Mixer and TCP graphics are still a bit slow/laggy to refresh. I see a flickery redraw when I expand the mixer for example, or if I scroll really fast (the mixer). It's also as if there's 2 resizes taking place (the first being redundant) when I resize the mixer. I don't know if these issues are related to yours. I am noticing these problems clearly on a low-end modern PC with the following: Athlon single-core 2.6GHz 2GB RAM Vista 32bit onboard ATI 780G (HD3200) graphics (Still, the graphics performance of the chipset is good enough for general use and even basic gaming, it's not a crappy system by any means.) edit: The track arming on the above system is almost instantaneous, even with 30 tracks at once. Reaper v2.54

I found the culprit: If I arm the tracks with a mouseclick all is fine -> tracks armed within a second. Now doing the same via keyboard shortcut causes this massive slowdown -> tracks get armed extremely slow one by one :( I even see this slowdown (with 40 tracks) on my fast Core2 Duo machine! Of course not that much as on the slower Pentium4 machine. Arming many via keyboard shortcut is much slower than arming via mouseclick!? Bug. @Evan (or other users with slow machines): Can you try it with keyboard shortcut? Thanks! FIXED (3.05pre2)

Shortcut is slower here 

Yep, I can confirm this. Arming 100 tracks with a shortcut is about 1 second. With a mouseclick is instantaneous. (with both V2.54 and alpha pre8) (This is with a Core2Duo @ 1.86GHz) Eddy
