How fast you are in unziping on Linux

REASON  
you might need to unpack many files in directory on Linux


Try sequential unzip

for i in `ls -1 | grep .zip$`; do unzip $i; done
or

ls -1 *.zip | xargs -n 1 unzip &

Parallel unzipping , be careful it may hang your host for a while

 for i in `ls -1 | grep .zip$`; do unzip $i &  done

Try gunzip tar

for i in `ls -1 | grep .zip$`; do tar xfvz $i; done
