Smerklo, however, said that, region by region, it's difficult to identify a global spending trend, but acknowledged plenty of positive signs. "The mood, when you're speaking to the CEOs of global technology companies, is generally a bit better than it was a year ago." John McAdam, the CEO of F5 Networks ( FFIV), said orders suggest robust revenue ahead. "We put in good sequential and year-over-year growth," he said during an interview following the networking specialist's fiscal first-quarter results. "We see the pipeline as pretty strong." F5 reaped the benefits of strong service provider spending during the quarter, despite concerns about the sector from networking giant Juniper ( JNPR). Semiconductor specialist LSI ( LSI) also put out strong numbers during its recent fiscal fourth quarter, with CEO Abhi Talwalkar saying the company is growing faster than its rivals. "Our guidance was very strong, ahead of all end markets," he told TheStreet. "We feel very comfortable in our ability to outpace the end markets and the majority of our peers." Bob Hammer, the CEO of storage specialist CommVault ( CVLT), said his firm hasn't suffered from weaker demand. "From a CommVault business perspective, we haven't seen any slowdown at all," he said after the company's recent record third-quarter results. "We just haven't seen it." Not every CEO, though, is as bullish. "I don't know that my crystal ball is good enough," said Bob Beauchamp, the CEO of BMC Software, which put out mixed fiscal fourth-quarter results last month. "There's too much uncertainty to forecast what spending is going to be in Europe." "The core issue for us continues to be rebuilding our sales force capacity," Beauchamp added. "We're really focused on building the sales channel -- we feel that we're channel-constrained."
