[Cdash] [EXTERNAL] Re: HIgh load and stalled submissions

[Wolfenbarger, Paul R]

I am using cdash 2-0-2 and mysql version 14.12.  I have made some changes
to the cdash php code myself, but they are mostly minor ones on the
display side and almost none on the submission side.  What tuning
parameters are you thinking of?
