I trade a whole lotta A/C/E, Globex, Eurex, and Liffe. Member/Seat Holder/registered trader in all. I know that Eurex has an older system... but it's never given me much to complain about in terms of stability and speed. Liffe likes to crash on a regular basis if you're trading it from the U.S.A.. And, Sashabr, I trade about 20,000 Euribor cars a month on Liffe, so experience, not some line of crap about bits and spread algorithms is in play here. I love Liffe products but I absolutely hate the platform. It screws EVERYBODY who isn't trading packs, strips, or bundles. Liffe could triple their volume if they let more flat price trade before the spread algorithm kicks in screws the rest of the orders who had time priority at that price. Liffe's reply? Well, improve your price! No, improve your algorithm. That's why Eurex gets the business. If you're first, you get them first.
