server hang with compression on, ping timeouts from remote machine
Hello All,
I am running NTFS over iSCSI on a ZFS ZVOL volume with compression=gzip-9 and blocksize=8K. The server is 2 core P4 3.0 Ghz with 5 GB of RAM.
Whenever I start copying files from Windows onto the ZFS disk, after about 100-200 Mb been copied the server starts to experience freezes. I have iostat running, which freezes as well. Even pings on both of the network adapters are reporting

gzip compression throttles system?
I just had a quick play with gzip compression on a filesystem and the
result was the machine grinding to a halt while copying some large
(.wav) files to it from another filesystem in the same pool.
The system became very unresponsive, taking several seconds to echo
keystrokes. The box is a maxed out AMD QuadFX, so it should have plenty
of grunt for this.
Comments?
