Small read size by Windows SMB client

fr flag

I am setting up a Linux server for high resolution online video editing. When I access the SMB share from a Windows 11 client, Wireshark analysis shows that the SMB Read requests are always a maximum of 256K in size. For efficiency I would like the disk accesses on the server to be larger.

In Linux when we mount a SMB share we can specify options like rsize. Are there similar options we can set in Windows clients when we are mapping a drive. Ideally I would like to set this to 1MB.

Note that this is not a restriction from the server side. When the negotiation happens the server advertises a Max Read Size of 8MB. Also the client's TCP Window size is much bigger.

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
