Hi, Which hardware will perform better for ISPconfig mail server Intel Pentium 4 - 2.0 Ghz or Intel Celeron 2.6 Ghz ? Both hardware have 512MB RAM.
Thats not easy to say without benchmarking. Maybe you will find some benchmarks on the intel website. Also it may make a difference how fast the harddisks in the systems are.
i would go for P4 over Celeron anyday. Celerons used to be cut down P4 cpus that failed tests thats why they sold them off as celerons...
