Short answer: Under excellent radio (signal/noise) conditions and decent but realistic client hardware, you should expect to see 600Mbps on 5GHz, and 100Mbps on 2.4GHz, from a device with the Wi-Fi radio capabilities the EAP225 seems to have.
Your EAP225 appears to support the an 867Mbps 802.11ac PHY rate by using 80MHz-wide channels, 2 spatial streams, MCS 9 (QAM-256) on 5GHz. With typical overhead, under excellent signal and noise conditions, a client capable of all those same Wi-Fi speed-increasing mechanisms should see TCP over IPv4 throughput as high as 600Mbps when talking to a device connected to a gigabit Ethernet LAN port of the EAP225. Please note that signal drops of dramatically as you move away form the AP, which means that PHY rates drop off dramatically as well. Also, noise on the channel, including other devices using the same AP, and other APs nearby using the same channel, will lower the expected throughput as well.
On the 2.4GHz band, your EAP225 appears to support the 450Mbps 802.11n PHY rate by using 40MHz-wide channels, 3 spatial streams, and MCS 15. However, most client devices only support 2 spatial streams, and anything that uses Bluetooth will ask the network to only use 20MHz-wide channels in order to leave room for Bluetooth, so those two vary common situation knock your expected PHY rate down to 144 Mbps, for an expected TCP over IPv4 throughput of 100 Mbps, again, under excellent RF conditions, and when talking to something on a gigabit Ethernet LAN port of the EAP225.
