I'm just taking a shot in the dark on this one, so don't flame me too
much if I am way off base--I am naked and weaponless...
Are the two systems you mentioned using hard drives with similar cache
sizes? I _think_ .wav files are created, played, and then deleted
during speech operation. If this is happening as you are keying in
information, these files will be created and deleted at a manic pace,
and a hard drive with a large cache will never actually spend time
writing these files onto its platters--they will be crated and deleted
entirely in the drive cache. A drive with a smaller cache will take
more time to write and delete the files because the mechanical
components have to physically move into position to get the job done.
Maybe this extra drive time is the culprit in your case???
The size of the drive cache on my Slackware system can be found in
and is listed in KB as 7936 (nearly 8 MB).
I vaguely recall something from long ago about a file system called
'tmpfs' (or something like it) which could be used to set up a /tmp
area in RAM--maybe this could help?
HTH a little, and have a great day.
