I expected the AES-GCM test to be proportional to the CPU test, but that's not the case. It's also less secure than AES-GCM, so we should not pay too much attention to these numbers, as everyone is encouraged to use AES-GCM these days. The performance scales roughly with the price.ĪES-CBC is an older, less performant algorithm. i5-6200U is approximately 2 times more performant than i5-4210U. TLSense i5-4200U is roughly twice as performant as APU with AES-CBC. The AES-CBC performance follows roughly the CPU performance from the previous chart. Let's compare two popular algorithms AES-CBC and AES-GCM. Encryption/Decryption performanceĪll CPUs have AES-NI support, so the encryption/decryption should be relatively fast. I was a little surprised about how good APU routers compare to the more expensive and more power-consuming CPUs. i7-6500U is approximately 130-180% more performant. i5-4210U is roughly 80-100% more performant than APU. As mentioned earlier, it also helps with routing multiple TCP connections concurrently. Multiple-core performance is important for applications that are multi-threaded such as Suricata or Wireguard VPN.

It's interesting that the most powerful router we sell is only about 4x more performant than APU in a single-thread CPU test. I3-4010U is just a little faster than APU. i5-4510U has roughly double single-thread performance of APU in single-core. Linux-based operating systems such as OpenWRT or IPFire don't have that limitation. For example Snort is single-threaded.īSD operating systems (pfSense and OPNsense) use one CPU core per TCP connection. The single-thread performance is essential for applications that can't take advantage of multiple CPU cores. The raw results are available in the text file, but that's a little dry to read and analyze so here's a read-only google spreadsheet with the data and charts Single-core CPU performance Sysbench -test=cpu -cpu-max-prime=50000 -time=30 run -threads=4Īnd these commands were executed to measure the encryption/decryption performance. Sysbench -test=cpu -cpu-max-prime=50000 -time=30 run -threads=2 sysbench -test=cpu -cpu-max-prime=50000 -time=30 run -threads=1 The following commands have been executed to measure raw CPU performance. Note, we measure 1 thread, 2 threads, and 4 threads. MethodologyĪll tests have been executed using sysbench 1.0.18 and openssl 1.1.1d on the Debian 10 4.19.0-9-amd64 system. For that reason, we have executed a CPU benchmark on all routers offered in the store. If you plan to run a VPN server/client on your router or IPS/IDS software, you may be interested in exact CPU performance before making a purchase. The data and charts in the spreadsheet are up to date - if you are looking for the new models view the source-data spreadsheet. Note: the text of this article is not updated with the latest models.
