In just a few years, Riverbed Technology (NASDAQ: RVBD) has built a strong technology offering, which helps move large files -- such as Microsoft (NASDAQ: MSFT) PowerPoints, SAP (NYSE: SAP) data files and so on -- across networks at high speeds. In fact, last week I had a chance to meet the CEO, Jerry Kennelly, who was quite upbeat even though Riverbed's stock price was down about 28% to $34.61.

Although, based on the fiscal Q3 results, things seem fine. Revenues spiked 158% to $63.3 million and net income was $2.8 million, or $0.04 per share, which compares to a net loss of $3.1 million, or $0.16 per share in the same period a year ago. About $9.7 million of Q3's expenses came from stock option compensation.

Riverbed has continued its innovation. Back in August, the company launched its Steelhead Mobile product, which improves the performance of file downloads for laptops. Riverbed claims that about 41% of workers in the US are mobile, such as in remote offices, hotel rooms, coffee shops and so on.

If you have ever had to deal with the slow response times of shared network software programs, you'll be able to appreciate the fact that there is a firm in San Francisco that can do something about it.

Riverbed Technology (NASDAQ: RVBD) provides hardware and associated software that speed the performance of shared computer network applications. The devices boost efficiency across wide area networks, routinely cutting business application times by factors of five and more. The company scales its systems to operate in environments ranging in size from small businesses to major data centers. Strategic partners include Hewlett-Packard (NYSE: HPQ) and EMC Corporation (NYSE: EMC). Cisco Systems (NASDAQ: CSCO) and Juniper Networks (NASDAQ: JNPR) are competitors.

The company pleased investors last week, when it reported Q1 EPS of twelve cents (ex-items) and revenues of $42.8 million. Analysts had been looking for five cents and $37.5 million. Management also guided Q2 EPS to 11-12 cents (six cent consensus) and Q2 revenues to $48-$49 million ($42.09M consensus).

In comments on his MAD MONEY this evening, Cramer was giving more advice for a record-breaking market. He said a great way to make money in a rally is to find some of the lesser-known names that have been overlooked.

[Oddly enough, this is a complete backflip from his advice last night, when he said to go with the big tech titans. But who's keeping track? Ahem.]

Today he said Riverbed Technology, Inc. (NASDAQ:RVBD) is one that could be a big big winner like his old DivX Inc. (NASDAQ:DIVX) call. He said RVBD is up 20% but you might not have missed it. He said they are actually beating Cisco Systems, Inc. (NASDAQ:CSCO) at its own game. Cramer said this is a great speculative tech stock.

Cramer said Riverbed is actually a best-of-breed WAN product company, but it isn't even profitable yet. He said the company's revenue growth has been large, and its technology is the best out there. Riverbed currently has deals with HP, McData, NEC, and others. He thinks the new estimates for RVBD are conservative, and it could blow away estimates one quarter out.

RVBD closed down 4% at $18.05 in regular trading but popped up 12% to $20.25 in after-hours after Cramer touted this stock.
