The recommendation to use a 1024-bit RSA key worries me. In an era of passive, bulk surveillance, that seems too weak if you're not going to be using any additional transport-layer security.
The performance argument is only relevant for the establishment of the VPN connection and any periodic rekeying — it shouldn't have any impact on the tunnel's perf.
It's a shame openvpn's easy-rsa doesn't provide a straightforward mechanism to generate ECDSA certificates, which would've removed any performance concerns.

edit: easy-rsa does support ECDSA[1]:
Support for generating an ECDSA certificate chain is available in EasyRSA (in
spite of it's name) since EasyRSA 3.0. The parameters you're looking for are
'--use-algo=ec' and '--curve=<curve_name>'. See the EasyRSA documentation for
more details on generating ECDSA certificates.
