[Table Syrup Records]

Ok, latest bounce of a session with around 60 tracks, hundred+ (~150ish?) of Waves V9(Latest Rev) Diamond Native + L316

Mac Pro QX 3.2
32GB RAM
System: 256 SSD (Crucial M4, OWC Tray, HDD Slot1)
Audio: Mac OEM (WD? 2TB 3.5 HDD Slot2)
2 Other 2TB HDDs for Samples and Archive - Not actively accessed in sessions
Latest Rev of Mountain Lion
PT 11.0.2 HD
HDN Card - 1st Slot next to Vid (5770)

EDITED TO ADD: Using 8GB Cache, at around 30% in this session

Other installs include Final Cut Pro X, Logic Pro X, DSP-Quattro
That's it

Currently no other SSD's (Had trouble with a Sonnet eSata PCIe Card, so removed)
Was wondering if my second 256 SSD in a PCIe host was an issue, so I removed it as well

Same issue:

Bouncing the session offline streams up around 25% complete, then gets slow - glitchy progress bar, updates roughly every 3 seconds, and basically ends in bouncing real time

Anyone else experience this?

I've been searching the forum here for offline bounce issues, and only seeing other issues I am not experiencing.

Stereo bounces through A 1/2

Further info:

HD I/O 16 on port one, with a 192 piggy backed
Sync HD and MIDI I/O
(Loop Sync'd)

Removing Sync HD, MIDI I/O and 192 makes no change

....

Always bouncing to include MP3 - Come to think of it I will try as WAV or MP3 only to see if that changes anything, but in the meantime, ^^^^^^
