It is significantly faster than the previous version. Here is the output of a 'yum check-update' : BEFORE Reading repository metadata in from local files primary.xml.gz 100% |=========================| 134 kB 00:00 update : ################################################## 393/393 Added 393 new packages, deleted 0 old in 7.98 seconds primary.xml.gz 100% |=========================| 510 kB 00:00 base : ################################################## 1500/1500 Added 1500 new packages, deleted 0 old in 22.19 seconds primary.xml.gz 100% |=========================| 100 kB 00:00 centosplus: ################################################## 356/356 Added 356 new packages, deleted 0 old in 5.09 seconds primary.xml.gz 100% |=========================| 157 B 00:00 Added 0 new packages, deleted 0 old in 0.01 seconds primary.xml.gz 100% |=========================| 35 kB 00:00 extras : ################################################## 139/139 Added 139 new packages, deleted 0 old in 1.61 seconds AFTER Reading repository metadata in from local files primary.xml.gz 100% |=========================| 134 kB 00:00 update : ################################################## 393/393 primary.xml.gz 100% |=========================| 510 kB 00:00 base : ################################################## 1500/1500 primary.xml.gz 100% |=========================| 100 kB 00:00 centosplus: ################################################## 356/356 primary.xml.gz 100% |=========================| 157 B 00:00 primary.xml.gz 100% |=========================| 35 kB 00:00 extras : ################################################## 139/139 The total time from the "before" run was 36.88 seconds.
