Ms loop

Accessed attributes in a product while iterating through a collection. Here’s the corresponding flame graph:Flame graph for a 10-item paginated collection with accessing to its attributes.The total render time of this loop is now at 162 ms, compared to 13 ms from the clean example. The product attributes access changes a less than one ms render time per tile to 16 ms render time per tile. This produces exactly the same markup as the clean example, but at the cost of 16 times more rendering time. If we increase the number of products to paginate from 10 to 50, it takes 800 ms to render.Tips:Instead of focusing on how many one millisecond bars there are, focus on the total rendering time of each loop iterationClean up any attributes that aren’t being usedReduce the number of products in a paginated page (potentially AJAX the next page of products)Simplify the functionality of the rendered productYou might also like: Working with Product Variants When Building a Shopify Theme.Nested loopsLet’s take that clean code example and make it render with nested loops.This code snippet is a typical example of iterating through the options and variations of a product. Here’s the corresponding flame graph:Flame graph for two nested loop example.This code snippet is a two-level nested loop rendering at 55 ms.Nested loops are hard to notice when just looking at code because they’re separated by files. But with the flame graph, we see additional rows representing them.Flame graph of a single loop on a product.As highlighted in the screenshot above, the two inner `for` loops stack side by side. This is okay if there are only one or two loops. However, each iteration’s rendering time will vary based on how many inner iterations it has.Let’s look at what a three-nested loop looks like.Flame graph for

Transit router, 'X' - unknown return code, 'x' - return code 0 Type escape sequence to abort. Destination address 127.0.0.1 ! ! Destination address 127.0.0.2 ! ! Destination address 127.0.0.1 ! ! Destination address 127.0.0.2 ! ! Entering the ping mpls command enables the router to send each packet size range for each destination address until the end address is reached. For this example, the loop continues in the same manner until the destination address, 127.0.0.5, is reached. The sequence continues until the number is reached that you specified with the repeat count keyword and argument. For this example, the repeat count is 2. The MPLS LSP ping loop sequence is as follows: repeat = 1 destination address 1 (address-start) for (size from sweep minimum to maximum, counting by size-increment) send an lsp ping destination address 2 (address-start + address-increment) for (size from sweep minimum to maximum, counting by size-increment) send an lsp ping destination address 3 (address-start + address-increment + address-increment) for (size from sweep minimum to maximum, counting by size-increment) send an lsp ping ... until destination address = address-end ... until repeat = count 2 Example: Possible Loop with MPLS LSP Traceroute The following example shows how a loop occurs if you use the following traceroute mpls command: switch# traceroute mpls ipv4 10.131.159.251/32 destination 127.0.0.1 127.0.0.3 1 ttl 5 Tracing MPLS Label Switched Path to 10.131.159.251/32, timeout is 2 seconds Codes: '!' - success, 'Q' - request not sent, '.' - timeout, 'L' - labeled output interface, 'B' - unlabeled output interface, 'D' - DS Map mismatch, 'F' - no FEC mapping, 'f' - FEC mismatch, 'M' - malformed request, 'm' - unsupported tlvs, 'N' - no rx label, 'P' - no rx intf label prot, 'p' - premature termination of LSP, 'R' - transit router, 'X' - unknown return code, 'x' - return code 0 Type escape sequence to abort.

Three nested loops.This three-level nested loop rendered at 72 ms. This can get out of hand really quickly if we aren’t careful. A small addition to the code inside the loop could blow your budget on server rendering time.Tips:Look for a sawtooth shaped flame graph to target potential performance problemsEvaluate each flame graph layer and see if the nested loops are requiredMix usage of multiple global Liquid scopeLet’s now take that clean code example and add another global scoped Liquid variable.And here’s the corresponding flame graph:Flame graph of when there’s one item in the cart with a rendering time at 45 ms.Flame graph of when there are 10 items in the cart with a rendering time at 124 ms.This flame graph is an example of a badly nested loop, where each variation is accessing the cart items. As more items are added to the cart, the page takes longer to render.Tips:Look for hair comb or sawtooth shaped flame graphs to target potential performance problems.Compare flame graphs between having one item and multiple items in the cart.Don’t mix global Liquid variable usage. If you have to, use AJAX to fetch for cart items instead.You might also like: How We Improved Theme Development Tooling Using Checksums.4.
