LISTSERV 16.5 - XROOTD-DEV Archives

We got gperftools installed & I re-ran the test with tcmalloc. The job reads 12 files stored on 12 different xrootd servers with a total size of 5.5GB. I also put those 12 files on a shared file system (GPFS). I used the LD_PRELOAD directive to switch between tcmalloc, jemalloc, and native malloc.

Reading files from GPFS, the process was stable using 100MB, independent of malloc
Reading files from xrootd: tcmalloc -> 123MB, jemalloc -> 134MB, native malloc -> 410MB

Both tcmalloc and jemalloc got rid of the large address allocation warnings from valgrind.
