Hi!
We are using SAP BI 4.1 SP 5 based upon Windows Servers. We are using a clustered environment, so we have to save our content on a NAS Storage, which could be accessed from all backend nodes.
We see some severe performance issues with this setup, if we try to schedule reports and save them in Excel format.
e.g. the scheduled WebI Document takes 60 seconds, the same report saved as Excel takes 1000 seconds.
After some investigation, we came to the point, that a direct write to the NAS(independently which one, we tried another windows server, we tried different NAS storages, ...) via SMB takes much more longer, as the data from the source(in our case oracle) has no continious flow, it will disrupt and wait, until the package is being written to the NAS. We can't see such a behaiviour, if we would write to local disk.
Is there a chance, to create Excel documents on the local disk or to keep them on a local cache, before they are transfered to the File repository, ?
Thanks and best regards,
Sebastian
