I'm running perf stat on the command ./start-server.sh -f server-config.xml:

perf stat -e cache-misses ./start-server.sh -f server-config.xml

I'd like to save the perf results to a file e.g. by appending &>out.txt to the command, however if I write the output to a file then I capture both the perf output as well as the start-server output. Is there a way for me to execute this command such that only the perf output will be written to the output file?

From perf help stat on my Debian 7:

-o file, --output file
Print the output into the designated file.

Try:

perf stat -o out.txt -e cache-misses ./start-server.sh -f server-config.xml
