Increasing TCP window size for Ontap httpd?


[...repost from]

The admin http server (i.e. for ZAPI) by default is using an extremely small TCP window (8760 bytes) that really slows down long operations (i.e. 'disk-list-info') for BDP connections.


This appears to be consistent across releases (at least 7.3.2 and 8.1RC2 exhibit the same behavior), but BURT 557123 suggest this hasn't always been the case (additionally, I wouldn't expect this to be acceptable for the WebDAV use case of the httpd).


Does anyone have pointers on how this can be increased?


(Would also love to get persistent connections for much the same reason, but implementation would obviusly be much more complex unless there was an easy way to shim in chunked responses).
