experience performance degradation.

Randy, try what is recommended here:

SENSEI-insitu/SENSEI#126

[rmcdermo]

Well, I don't have the problem when I compile and run locally. I don't think this is something we should expect users to need to do.

[rmcdermo]

Yes, adding export TMPDIR=/tmp removes the error message.

[cxp484]

I am not getting the error because for me MacOS automatically defined a TMPDIR environment variable as follows:

echo $TMPDIR
/var/folders/qq/nhw6cyzs2fdf_3bms4st1k9r002c63/T/
