Do you know where this (seeming) throughput limitation is _actually_ occurring?
I don’t know what format you are getting the data in, but if each stock is represented by it’s 1-4 character symbol, followed by a current quote (perhaps both bid and asked), then this adds up to around a dozen characters.  Lets be generous and say 20 bytes.  Twenty bytes times 1000 stocks is 20 kB.  Even a “slow” connection these days should give you a 2 Mbs throughput or 200 kBs (including overhead), so your 20 kB of data should download in roughly one tenth of a second.

In other words, don’t waste time solving the wrong problem.
