Need for speed–Benchmarking Citrix NetScaler
Citrix has announced the move to more NFV and pushing the limits of NetScaler towards up to 100GBps on a single VPX (Yet to see) but since this was a hot topic a week back I decided to benchmark a VPX to see what it can actually deliver in terms of performance over SSL.
Now I love the VPX is a good piece of software and is supported on most hypervisors, so therefore I wanted to give this a try using the Apache benchmarking tool abs (S is for secure)
Now from the Citrix datasheet, the VPX has the following attributes
The most important one is that it can handle UP to 750 SSL transactions/sec which contain 2K certs. This was my main objective to test the amount of transactions it could handle to see if it could live up to the claim and if we can do anything to tweak the results.
Now when setting this up I decided to do an isolated test within an ESXi host, to make sure I was not losing any perfomance on our crappy network cards. The host itself was not constrained in any matter…
