概要
FIPS無しのOpenSSLが必要だったので、自分でビルドしました。 比較するバージョンが違っていますが、以下のバージョンを比較しました。
- 自分でビルドした 1.0.1p
- 自分でビルドした 1.0.1p fips
- OpenSSL 1.0.1e-fips 11 Feb 2013
結論
自分でビルドした 1.0.1p のほうが 1.0.1e-fips よりと若干高速でした。

ビルド方法
FIPS無効
tar zxfp openssl-1.0.1p.tar.gz cd openssl-1.0.1p sudo yum install zlib-devel sh config zlib make
FIPS有効
先にfips用のライブラリをビルドします。
wget https://www.openssl.org/source/openssl-fips-2.0.10.tar.gz tar zxfp openssl-fips-2.0.10.tar.gz cd openssl-fips-2.0.10 sh config zlib make sudo make install
tar zxfp openssl-1.0.1p.tar.gz cd openssl-1.0.1p sudo yum install zlib-devel sh config zlib fips make
