Hi, as with anything the way they may have their server up is almost completely different and therefore cannot be compared. We currently have a plugin similar to this which seems to do the same stuff. But the use of this plugin to really reduce 'lag' can really change the survival experience for some as its main use is the removal of entities which for us could not be a good idea. Currently, we are looking into areas to help improve/fix the lag issue. We have made great strides towards a better experience for all.
