copied!<p>If your StockModel.Quotation class allows for it, you could create a pool to limit the number of new objects created. This is a technique they sometimes use in games to prevent the garbage collector stalling in the middle of renders.</p> <p>Here's a basic pool implementation:</p> <pre><code> class StockQuotationPool { private List<StockQuotation> poolItems; private volatile int itemsInPool; public StockQuotationPool(int poolSize) { this.poolItems = new List<StockQuotation>(poolSize); this.itemsInPool = poolSize; } public StockQuotation Create(string name, decimal value) { if (this.itemsInPool == 0) { // Block until new item ready - maybe use semaphore. throw new NotImplementedException(); } // Items are in the pool, but no items have been created. if (this.poolItems.Count == 0) { this.itemsInPool--; return new StockQuotation(name, value); } // else, return one in the pool this.itemsInPool--; var item = this.poolItems[0]; this.poolItems.Remove(item); item.Name = name; item.Value = value; return item; } public void Release(StockQuotation quote) { if (!this.poolItems.Contains(quote) { this.poolItems.Add(quote); this.itemsInPool++; } } } </code></pre> <p>That's assuming that the StockQuotation looks something like this:</p> <pre><code> class StockQuotation { internal StockQuotation(string name, decimal value) { this.Name = name; this.Value = value; } public string Name { get; set; } public decimal Value { get; set; } } </code></pre> <p>Then instead of calling the new StockQuotation() constructor, you ask the pool for a new instance. The pool returns an existing instance (you can precreate them if you want) and sets all the properties so that it looks like a new instance. You may need to play around until you find a pool size that is large enough to accommodate the threads at the same time.</p> <p>Here's how you'd call it from the thread.</p> <pre><code> // Get the pool, maybe from a singleton. var pool = new StockQuotationPool(100); var quote = pool.Create("test", 1.00m); try { // Work with quote } finally { pool.Release(quote); } </code></pre> <p>Lastly, this class isn't thread safe at the moment. Let me know if you need any help with making it so.</p>
