EV exports are slow, what can be done to improve performance?
So on the properties of your Storage service on the Advanced tab what are your settings?
Also, please do the Export to a local drive and report what kind of throughput you see.
You need to provide a little more information.
1. What version of EV?
2. What is the storage device for the Vault Store?
3. What are the spec's of the EV Server?
4. How are you doing the export? Via a webapp search or Export wizard
5. What throughput are you seeing?
really need more information to be honest
What are you constituting as being slow?
How are you determining that it's slow?
Has it ever been fast?
What has changed in the environment that might make it slower?
How are you doing the exports? Through the VAC? through DA?
Are you exporting to a PST file or to an exchange mailbox?
What kind of storage do you have? what version of EV do you have?
What version of windows do you use? what version of SQL Server do you use?
Are you seeing CPU spikes on the EV Server?
Are you seeing CPU spikes on the SQL Server?
Are you seeing any network issues, dropped packets or anything like that?
Are you seeing any errors in the Enterprise Vault logs? Application logs? system logs?
Are you exporting to a local drive or are you exporting to a network drive?
What version of Outlook do you have installed on the EV Server?
Are you running the export on the same server that hosts the Storage Service for that archive?
(ie is your user on a vault store hosted by EVServer1, but you're running the export on EVServer2)?
What is the link speed between the EV Server and the storage medium
What is the link speed between the EV Server and the SQL Server?
Does your EV server have TCP Offload (TCP Chimney) enabled?
Does your SQL Server have have TCP Offload (TCP Chimney) enabled?
Do you have Anti virus excluding your temp directory?
Do you have Anti virus excluding your export directory?
Too many questions and just not enough information

EV Performance guide:
Export to PSTs
On a server with 4 CPUs, items may be exported to PSTs at the rate of 30,000 items an hour. If a higher rate is required, five export processes can be started, giving a maximum rate of 100,000 items an hour.
What are you constituting as being slow? export (43,000 messages per 7 hours)
How are you determining that it's slow?
Has it ever been fast? Performance guide (30,000 messages per 1 hour)
What has changed in the environment that might make it slower? no
How are you doing the exports? Through the VAC? through DA? VAC
Are you exporting to a PST file or to an exchange mailbox? PST
What kind of storage do you have? what version of EV do you have? NETAPP
What version of windows do you use? what version of SQL Server do you use? Wind 2008, SQL 2005
Are you seeing CPU spikes on the EV Server? NO
Are you seeing CPU spikes on the SQL Server? NO
Are you seeing any network issues, dropped packets or anything like that? NO
Are you seeing any errors in the Enterprise Vault logs? Application logs? system logs? NO
Are you exporting to a local drive or are you exporting to a network drive? network drive
What version of Outlook do you have installed on the EV Server? 2003
Are you running the export on the same server that hosts the Storage Service for that archive? yes
(ie is your user on a vault store hosted by EVServer1, but you're running the export on EVServer2)? NO
What is the link speed between the EV Server and the storage medium? 1Gbps
What is the link speed between the EV Server and the SQL Server? 1GBPS
Does your EV server have TCP Offload (TCP Chimney) enabled? not sure
Does your SQL Server have have TCP Offload (TCP Chimney) enabled? not sure
Do you have Anti virus excluding your temp directory? yes
Do you have Anti virus excluding your export directory? yes
So on the properties of your Storage service on the Advanced tab what are your settings?
Also, please do the Export to a local drive and report what kind of throughput you see.
Archive processes: 5
Restore processes: 2
Restore threads per process: 3
Export throughput:
Local drive: 43000 messages - 4 hours
Network drive: 43,000 messages - 7 hours
Are you using collections?
Remember that if you are exporting 'old archived items', EV needs to unpack the cabfile, extract the necessary files, export them. That could slow down too.
