Revised mostly for style (#104)

- heading followed by intro sentence
- present tense
- command follows the reference item
- bullets only for multiple items, though if more limitations are found, then I would put the bullet back

 # Performance
+Performance testing against our lab configuration produces the following results and limitations. 
 
 ## Tested Configuration
 
-* SC4S instance requesting 8 cores and 4 GB of memory with K8S scheduler.

+The single syslog-ng container in this test is able to provide effective balancing and routing of events equivalent to 632 GB per day:

 average rate = 9717.58 msg/sec, count=1749420, time=180.026, (average) msg size=800, bandwidth=7591.86 kB/sec

 ```
 
 
 ## Limitations
 
-* Splunk Enterprise's implementation of the http event collection server will respond to the client with a status code 200 and fail to commit the events to disk during a rolling restart in our testing 20-30 events per indexer may be lost
