This is on the money from my experience. Since upgrading my system to dual-core with beaucoup RAM, I no longer have any problems with "freezing" or "slowdown". Also, compared eSignal with DTNIQFeed, head to head with respect to fidelity of the data feed and they are entirely comparable. BOTH miss some trades (I have an INET feed and can clearly see missed trades). Recently DTN has been upgrading its servers and that may cause problems for some traders (in fact I know some traders have cancelled DTN and moved elsewhere because of this problem). It should be temporary but time will tell. lj
