AltostratusQuestions about performance degradation when used with DNS features in GTM solutions
MVPThanks for the translate whisperer
It might be worth to talk with a local F5 partner / reseller, probably easier with language and such.
In general dedicated F5 appliances / software doesn't behave worse and often better then general solutions. So not sure where the idea about sloweness comes from.
You can stop looking for GTM, the module is simply called DNS now. If yours is still called GTM you might be running quite old versions, which TMOS version is it?
MVPboneyardYou are incorrect sir. F5's own documentation confirms that I have said: https://my.f5.com/manage/s/article/K000132353. Every single Channel Engineer over the past 15 years I have been working with GTM and DNS also confirms. Additionally, I actually helped write the exam questions for the 302 exam.
- Performance
DNS Express loads the whole zone files into BIGIP memory, and leverages BigIP TMOS capacity to handle client queries. Its performance is far better than a BIND server, especially for TCP-based DNS requests.
I would NOT recommend running DNS only from BIND directly on the F5 DNS (formerly GTM) product. Plain and simple. It is also a disaster to maintain zones.. zonerunner? I would instead recommend BIND (if you dont care about IPAM and your amount of data is minimal) with Zone Trasnfer internally to localhost and DNS Express OR use a better IPAM equipped system like Infoblox and zone trasnfer to DNS Express. If using DNS Express on F5 DNS or even WIPs, then the performance will trump any competitor any day of the week (that I do agree with). However, straight from BIND on F5 DNS... NO!
