~/.subversion/servers contains a line that's tunable, right: # http-compression = no
And per comment, tack on: --config-option=servers:global:http-compression=no . I'll report back the results. How is Apache and its modules organized? As separate processes - with TCP/IP between each? If yes, is that interconnect loopback Unix domain sockets? Or is it the same process, with buffers via malloc, and a plugin architecture mean a single stack between Apache and the chain of modules into Svn? Or is there a temp-file situation happening - modules put/pickup payloads (or maybe large payloads only) from the root FS as part of the delegation? Could there be swap file issues here, on the 4GB machine? Some condition that manifests itself with Apache and 500MB payloads in play, but not 'cp' of the same resource? Oh, thanks for checking with your people, Jack. - Paul
