Hi, after 4 Weeks of successful testing in our GS infrastructure we just enrolled a dns caching service on all machines in our datacenter to reduce dns querys to our DNS Server and overall sessions on our Firewall. This works as expected and we reduced about 140.000 Sessions. We also expect overall network perfornmance improvements on establishing connections to internal and external services using DNS. persons responsible: DGO GMA -- Mit freundlichen Grüßen Denny Gommel - Systemadministration - _______________________________________________ TraSo GmbH Nonnenstraße 42 04229 Leipzig Tel.: +49 341 / 355 740 -73 Fax: +49 341 / 355 740 -21 E-Mail: d.gommel@traso.de Internet: https://www.traso.de GPGP: 0xB1300DEE _______________________________________________ Geschäftsführer: Haiko Gerdes Handelsregister: Amtsgericht Leipzig (HRB 21850)
