Huang:
If you want to gather performance numbers , you can use the function
"gossip_err("put whatever you want to display in here. works like
printf\n")" and the data will be displayed in each server's log file. For
the default alt-aio trove method, the actual write to disk is performed in
the function alt_lio_thread() in <OFS
dir>/src<http://localhost:8080/source/xref/stable-20120815/src>
/io
<http://localhost:8080/source/xref/stable-20120815/src/io>/trove<http://localhost:8080/source/xref/stable-20120815/src/io/trove>
/trove-dbpf<http://localhost:8080/source/xref/stable-20120815/src/io/trove/trove-dbpf>/dbpf-alt-aio.c.
Does this help?
