RaptureXML kind of slow

I've recently switched from TBXML to RaptureXML, and even though pulling in information is much easier, there is a noticeable delay when I tap the tab bar button containing my xml table view.

In my viewDidLoad method I have the following"

events = [[NSMutableArray alloc] init];
 
 [self loadURL];
 

And my loadURL method is the following:

- (void)loadURL {
 
 RXMLElement *rootXML = [RXMLElement elementFromURL:[NSURL URLWithString:@"http://api.somexml.com/xml"]];
 
 [rootXML iterateWithRootXPath:@"//event" usingBlock:^(RXMLElement *event) {
     [events addObject:[NSArray arrayWithObjects:
                        [event attribute:@"uri"],
                        [event attribute:@"displayName"],
                        [event attribute:@"type"],
                        nil]];  
 }];
 
 [rootXML iterateWithRootXPath:@"//location" usingBlock: ^(RXMLElement *location) {
     [events addObject:[NSArray arrayWithObjects:
                        [location attribute:@"city"],
                        [location attribute:@"lat"],
                        [location attribute:@"lng"],
                        nil]]; 
 }];
 
 [rootXML iterateWithRootXPath:@"//start" usingBlock:^(RXMLElement *start) {
     [events addObject:[NSArray arrayWithObjects:
                        [start attribute:@"time"],
                        [start attribute:@"date"],
                        nil]]; 
 }];
 
 
 
 }
 

Is there something I can do to speed it up? Also when I assign my row count as [events count] I'm getting 19 rows when I should only get 6. Please help.
