In response to Jordan Desroches <[EMAIL PROTECTED]>: > Compression is not enabled in the FileSet.
Can you isolate where the bottleneck is? IO? CPU? Network? There are frequently discussions about throughput being sub-optimal on the lists. In my experience, these fall into a few categories: *) The SQL server is the bottleneck. This kinda falls outside the discussion of Bacula, as it's usually specific to the particular SQL server you use. This problem shows up most often with filesets that contain lots of little files. However, there _has_ been work done to improve how Bacula writes to the database, so which version you're using is important. If you can make any suggestions on how to improve this further, or even provide test cases to show where it's slow, I expect it will be helpful to the developers. *) IO. Often, folks are saturating the IO of their hardware and don't realize it. This can show up when the database is on the same system as file volumes, as that system has to share the IO of database writes as well as file volume writes. *) Mysterious network problems. This is the one that it would be nice to get some real information on. Some folks have claimed that Bacula is unable to send data anywhere near the speed of the network, even when there is no other bottleneck. Unfortunately, this problem has been very difficult to diagnose, as it requires a high level of expertise in networking to track down the cause, and everyone who has report it has been unable and/or unwilling to isolate it well enough for anyone to really do anything to improve it. So, I hope that information is helpful in narrowing down your problem. > Michel Meyers wrote: > > -----BEGIN PGP SIGNED MESSAGE----- > > Hash: SHA1 > > > > Jordan Desroches wrote: > >> Greetings! > >> > >> First, I apologize if this comes through multiple times.
