Re: slower https transfer speeds compared with rsync/smb/sftp

[Adam Teale <adam@xxxxxxxxxx>]

I have tried setting SendBufferSize to all many different amounts but it doesn't affect the transfer speed.

mod_info:

Current Configuration:

In file: /Library/Server/Web/Config/apache2/httpd_server_app.conf

 460: StartServers 4

 461: MinSpareServers 3

 462: MaxSpareServers 10

 463: ServerLimit 256

 464: MaxClients 256

 466: SendBufferSize 1042560

Hi Yann! Thanks for your help.

The value for sendspace is "1042560"

​What does that value mean? Is that how many bytes per packet​ can be sent at a time?

​At that current setting the downloads sit at around 34MB/second.

I appreciate your help, cheers!

It defaults to the value of the system, so possibly on Mac OS the
value of "sysctl net.inet.tcp.sendspace"?
