Thanks for the help. So to force the use of `xrdcp` command, I recompiled a custom xrootd modifying line 55 of `XrdXrootdPgrwAio.hh` (new line `static const int aioSZ = 1024*1024`) and it's working as expected. Any way to change it using some env variable? (tried with XRD_CPCHUNKSIZE but it seems not to be the right param). After that, I tried to mount the directory xrootd as a FUSE. In my config I disabled the `sendfile` option (not implemented by the plugin): ``` xrootd.async force limit 8 maxsegs 8 maxstalls 5 maxtot 4096 segsize 1024k nosf ``` and from the client side: ``` xrootdfs -o rdr=root://localhost:8094/my/directory,uid=daemon /my/mount/point cp /my/mount/point/big.bin ./ # big.bin is 10MiB ``` but this time I am getting async-read request (i.e. `aio_nbytes`) of 131 KiB (still not `1MiB`). What am I doing wrong? -- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/issues/1694#issuecomment-1113015435 You are receiving this because you are subscribed to this thread.
