Hi, I have created PR#237860 to keep track of a patch I have to try and improve the performance of mountd when reloading exports for an NFS server with a lot of file systems. Peter reported that the nfsd threads would be stalled for 16sec when exports were reloaded (via SIGHUP) for his file server with 72000+ file systems on it.
Peter will be testing this patch, but I would appreciate it if anyone else can test it as well. It doesn't matter if your NFS file server only exports a few file systems, because I would like to find out if the patch results in any regressions. (The new capability of incrementally updating the exports in the kernel upon a reload is only enabled if mountd is started with the new "-I" option the patch adds.) If anyone can test the patch (it is the attachment in the PR), please let me know how it goes. Thanks, rick _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[email protected]"
