Hello everyone, We are trying to track down some samba issues and wondering there are some settings we can tweak. We have a new Supermicro server running the following with 192GB of RAM, 32 active CPUs and 54TB of usable zfs mirrors (raid10). uname -a FreeBSD hostname 11.1-RELEASE-p4 FreeBSD 11.1-RELEASE-p4 #0: Tue Nov 14 06:12:40 UTC 2017 root at

There are a number of rather low listen() queue limits in Samba which we also ran into on our pretty busy (around 300-500 users/server) Samba servers, also on FreeBSD 11.1 (six servers with 256GB RAM, 2x10Gbit ethernet, 140TB of storage). Please find enclosed a patch we use to up the limits (quite a bit). The patch makes it possible to control the queue limit via the config file using a “socket listen backlog” parameter. We set it to 1024 on our servers. With the default (10) things go wrong too often....

Hi all, I need some suggestions or hints which syslinux version I shall use. The main focus will be on PXE boot. I have to upgrade due to (expected) performance problems (tftp), so I will swich to HTTP boot ! existing system: - syslinux version 4.05 (tftp only) - used modules : pxelinux.0, memdisk, vesamenuc32, patched startrom.0 - I boot .nbi , .iso, .ima and sometimes files (clonezilla etc.) -
