At present, we're trying this out on a single server. However, the CPU and RAM 
are nowhere near maxed out during a crawl. I've been through everything I can 
think of, and all I can see is the low network traffic. But not sure if it is 
cause or a symptom.

I'll try turning off indexing on the server drive. Can't see anywhere else to 
go at the moment.

What's your farm topology like? Is crawling happening from a specific 
application server, multiple application servers or is it crawling from an 
'all-in-one' single SharePoint server that also serves user web requests? This 
could potentially be due to the fact that the server is taking a bit of time 
for crawling and indexing each individual document, which then impacts the rate 
it can crawl at.

What's CPU, RAM, Disk and Network activity like on the server during the 
crawling?
Apart from disabling Antivirus, you can also try disabling the Windows Search 
indexer, right click the disk drive in Windows Explorer and select properties, 
untick the "Allow files on this drive to have contents indexed in addition to 
file properties" although this probably won't solve your specific issue...

At the rate our crawl was running, that would have taken more than 2 hours.

Hi Dylan,

How does it work with copying a large from share to server/vice versa? Is the 
speed issue replicated?

After exhaustive examinations by the data centres guys here, we can't see why 
the crawl is so slow.

The bottleneck appears to be network performance. During an entire crawl (about 
80 hours) network traffic to and from Sharepoint server sits at about 10Mbps. 
Both the server and the location of the crawled files have NICs capable of 
scaling traffic up to 10Gbps. We observe traffic overnight as server backup is 
performed of around 400Mbps (which is occurring on top of the crawl.)

There is no disk latency issue on our SharePoint infrastructure.

Stumped.

Time to call Microsoft?

I know we're crawling a DFS, with the actual content on a variety of servers. 
The majority of it is on a single SAN though.

I'm trying to see if there are any obvious slowdowns, but having trouble 
locating the logging data. When I go to 
http://[ourserver]:[centraladminport]/_admin/search/logviewer.aspx?appid={26cbdb93-9472-4690-8e5f-409e72d802a9}
 I get a list of crawled items, but it is in a daft 50-to-a-page format that is 
difficult to do any analysis with.

Is there another place I can obtain this info that is more queryable?

Are they all on the same subnet? Are there network QoS policies in place that 
are affecting the search server from crawling that share?  What storage 
infrastructure is hosting the 40GB of files?

Seems rather odd though, we're crawling 400+GB in under 8 hours for a full 
crawl so something is amiss with your config.

Thanks Sezai.

No crawler impact rules here.

We've only crawled this share once, so it has always taken this long, I guess. 
I also suspect latency/bandwidth issues, as we seem to have network traffic 
moving at about 100Mbps onto that server.

(I've checked a bunch of other metrics out in relation to RAM, CPU, and even 
the OSS performance monitor stuff, and it all seems normal.)

Has indexing that specific file share ever completed any faster?
It could be the network link (latency & bandwidth?) between the SharePoint 
server doing the crawling and the file share?

Another thing to check is if there is a Crawler Impact Rule configured, review 
this in the Search Service Application, ensure there aren't any configured for 
that specific file share.

You can configure a max limit to the number of simultaneous requests, or set a 
specific time in seconds for the crawler to wait between requesting each 
document. This is handy to prevent a content source from being saturated by 
your crawler. It does take the crawler longer to complete crawling if these are 
configured.

I reckon it's a network latency & bandwidth issue :)

Sharepoint 2010

Someone here recently switched on a file share crawl on a network share, and it 
is running really slowly.

(Last incremental crawl took about 140 hours to crawl about 40GB of files.)

I've looked around a bit, but having trouble working out how to determine what 
the bottleneck in the process might be.

Another incremental crawl is running right now, and has been going for over 40 
hours.

Any suggestions what I should be looking at?

Cheers,
