Manish, The slowness could be because ZFS cache has hogged up the memory. You can limit the cache size to 1GB by setting the value of zfs_arc_max. I don't remember the exact variable.
Search for "limiting zfs arc" on the zfs-discuss alias and you should be able to get the details. This is problem in your case because, the zfs cache would have grown during the build. Now when you login the JDS binaries which sit on UFS need to be loaded and that needs to throw out what ZFS cached. This is right now is not very smooth and hence you could be seeing the sluggishness.... The NWAM dropping the line possibly means the signal seems to be dropping at times... I use it at home for days without any issue (infact I am punched in to office network for over a day). Cheers, Sanjeev.
