hello Smile
got a question about the buffer sizes
my download speed is over 100 mbps and so is upload speed.
i have my send and receive buffers set to 2 MB each
inside my network adapter settings my transmit buffer is 128(max)
my receive buffer is 512(max)
i cannot push the settings inside my adapter settings higher.
so will apache use the 2 mbs for each buffer overriding the adapter settings?
and is 2 mb too high for each setting?
my adapter is realtek pcie gbe family controller using the latest driver.
windows 10 home os

Are you talking about BufferSize[1] ?? if yes it makes no sense to use it for that purpose.

Quote:
Under certain circumstances, content generators might create content in small chunks. In order to promote memory reuse, in memory chunks are always 8k in size, regardless of the size of the chunk itself. When many small chunks are generated by a request, this can create a large memory footprint while the request is being processed, and an unnecessarily large amount of data on the wire. The addition of a buffer collapses the response into the fewest chunks possible.

Yes, the default value uses the OS / Windows values from your network card.

Also, the send buffer works only with static files.
IMHO leave the settings as is.
